Grams to Cups: Conversion Guide, Charts & Calculator

Trying to turn a recipe written in grams into cups? Grams to cups conversion trips up more home cooks than almost any other kitchen math problem and it's not your fault.

A gram measures weight. A cup measures volume. The two only line up once you know how heavy your ingredient is. That's why one grams to cups converter for flour won't work for sugar, honey, or milk. Every ingredient has its own density, so a cup of flour and a cup of honey never weigh the same.

These numbers use standard US cup measurements (236.6 mL). Densities can shift slightly by brand and how you pack the cup see the full chart further down for more ingredients and amounts.

What Is a Gram?

A gram is a small unit of weight in the metric system. It's tiny a paperclip weighs about 1 gram, and a regular egg weighs around 50 grams.

Grams measure mass, not space. That's the key fact behind every gram to cup conversion on this page. Whether you're weighing flour, sugar, or salt, 100 grams is always 100 grams no matter how fluffy or packed the ingredient looks.

Bakers outside the US usually measure in grams because a kitchen scale removes guesswork. You place your bowl on the scale, tare it to zero, and pour until you hit your target weight. No scooping. No leveling. No arguing about how "full" a cup should be.

What Is a Cup?

A cup is a unit of volume, not weight. In the US, one cup equals 236.6 milliliters (some measuring cups round this to 240 mL).

Here's where it gets tricky cups aren't the same everywhere:

• US customary cup: 236.6 mL
• US legal cup: 240 mL
• Metric cup (used in Australia, the UK, and many recipe sites): 250 mL
• Imperial cup (older UK recipes): 284.1 mL
• Japanese cup: 200 mL

If a recipe doesn't say which cup it means, most US recipes assume the US customary cup. This guide uses that standard throughout.

Because a cup measures space, not weight, the real question is never just "how many grams for a cup?" It's "how many grams for a cup of this ingredient?" A cup of feathers and a cup of sand take up the same space but weigh very differently. Flour and sugar work the same way.

How to Convert Grams to Cups

Converting grams to cups takes three simple steps:

1. Identify your ingredient. All-purpose flour, granulated sugar, and honey all convert differently.
2. Find its grams-per-cup value. Check the charts further down this page, or use the converter above.
3. Divide your gram amount by that number. The result is your answer in cups.

Here's the shortcut formula:

Cups = Grams ÷ Grams per Cup

Example: you need to convert 250 grams of flour to cups. All-purpose flour weighs about 125 grams per cup, so:

250 ÷ 125 = 2 cups

That's the whole method. The only real work is knowing the right grams-per-cup number for your ingredient which is exactly what the charts on this page give you.

100 Grams to Cups

100 grams is one of the most-searched amounts, since it's a simple starting point for scaling a recipe. Here's how 100 grams looks across popular ingredients:

Ingredient	100g in Cups
All-Purpose Flour	0.8 cups
Granulated Sugar	0.5 cups
Brown Sugar (packed)	0.45 cups
Butter	0.44 cups
White Rice (uncooked)	0.54 cups
Milk	0.41 cups
Rolled Oats	1.11 cups

How Many Cups Is 100 Grams of Flour?

100 grams of all-purpose flour equals about 0.8 cups a little under 1 cup. On a standard US measuring cup set, that's closest to ¾ cup plus 2–3 tablespoons. For an exact result, weigh it on a scale instead of guessing between cup sizes.

200 Grams to Cups

Ingredient	200g in Cups
All-Purpose Flour	1.6 cups
Granulated Sugar	1 cup
Brown Sugar (packed)	0.91 cups
Butter	0.88 cups
White Rice (uncooked)	1.08 cups
Milk	0.82 cups
Rolled Oats	2.22 cups

How Many Cups Is 200 Grams of Flour?

200 grams of all-purpose flour equals about 1.6 cups that's 1 cup plus a scant ⅔ cup. Some recipes round this to 1½ or 1¾ cups, so check where your recipe comes from if the number looks off.

250 Grams to Cups

Ingredient	250g in Cups
All-Purpose Flour	2 cups
Granulated Sugar	1.25 cups
Brown Sugar (packed)	1.14 cups
Butter	1.1 cups
White Rice (uncooked)	1.35 cups
Milk	1.02 cups
Rolled Oats	2.78 cups

How Many Cups Is 250 Grams of Flour?

250 grams of all-purpose flour equals exactly 2 cups. This is one of the easiest conversions to remember, which is one reason many European recipes are written in 250-gram steps it lines up neatly with US cup sizes for flour.

When to Convert Grams to Cups

You don't always need to convert. If you own a kitchen scale, grams are often easier to use directly. But there are real situations where switching to cups makes sense:

• Your recipe comes from Europe, Asia, or Australia, where grams are the norm.
• You're baking with someone who only owns cup measures.
• You want to scale a recipe up or down and prefer thinking in cups.
• Your scale's battery just died and you need a backup method.
• You're teaching someone to bake and cups feel more familiar to them.
• An old family recipe uses cups, but a newer version (or a substitute ingredient) is listed in grams.

Whatever the reason, the same rule applies: know your ingredient before you convert.

Grams to Cups Formula

The core formula behind every conversion on this page is:

Cups = Grams ÷ Grams per Cup

If you want the more technical version, using cup volume and density:

Cups = Grams ÷ (236.6 × Density in g/mL)

Both formulas give the same answer. The first one is just easier to use every day.

Worked Examples

• 180g flour: 180 ÷ 125 = 1.44 cups
• 300g sugar: 300 ÷ 200 = 1.5 cups
• 400g butter: 400 ÷ 227 = 1.76 cups
• 500g honey: 500 ÷ 340 = 1.47 cups

Keep the grams-per-cup chart below bookmarked, and this formula works for any ingredient you need.

Why There Isn't One Universal Formula

You might wonder why there's no single number that works for every ingredient. The answer comes down to density.

Grams measure weight. Cups measure volume. The relationship between the two changes for every ingredient because every ingredient packs into a cup differently.

Think of it this way: a cup of popcorn weighs almost nothing. A cup of honey feels like a small brick. Both fill the same 236.6 mL of space, but their weights are worlds apart.

That's why a single "grams to cups converter" formula would fail the moment you switched ingredients. Flour, sugar, oil, and rice all need their own grams-per-cup value which is exactly why this page has a separate chart for each one.

How to Calculate Ingredient Density

If you ever need a grams-per-cup value that isn't listed here, you can measure it yourself:

1. Place an empty measuring cup on a kitchen scale and set it to zero (tare).
2. Fill the cup using the correct method for that ingredient (spooned, packed, or leveled).
3. Read the weight in grams. That number is your ingredient's grams-per-cup value.
4. To get density in g/mL, divide that number by 236.6 (the volume of a US cup).

Example: if 1 cup of chopped walnuts weighs 120 grams, your grams-per-cup value is 120, and the density is 120 ÷ 236.6 = 0.51 g/mL.

Once you have that number, you can convert any gram amount of that ingredient using the same formula as everything else on this page.

Why Density Matters

Density is the reason every grams to cups conversion needs an ingredient name attached to it. Here's a clear side-by-side, all for the exact same cup:

• 1 cup of all-purpose flour = about 125 grams
• 1 cup of granulated sugar = about 200 grams
• 1 cup of butter = about 227 grams
• 1 cup of honey = about 340 grams

That's close to a 3x difference between the lightest and heaviest ingredient on this list.

Ignoring density is the single biggest reason online converters and printed charts give wrong answers. If a chart doesn't ask which ingredient you're measuring, don't trust its numbers.

Flour Conversion Chart

Not all flour weighs the same. Here's how 100g, 200g, 250g, and 500g convert across common flour types:

Flour Type	Grams per Cup	100g	200g	250g	500g
All-Purpose	125g	0.80 cups	1.60 cups	2.00 cups	4.00 cups
Bread Flour	127g	0.79 cups	1.57 cups	1.97 cups	3.94 cups
Cake Flour	114g	0.88 cups	1.75 cups	2.19 cups	4.39 cups
Whole Wheat	120g	0.83 cups	1.67 cups	2.08 cups	4.17 cups
Self-Rising	125g	0.80 cups	1.60 cups	2.00 cups	4.00 cups
Almond Flour	96g	1.04 cups	2.08 cups	2.60 cups	5.21 cups

Rice Conversion Chart

Rice Type	Grams per Cup	100g	200g	250g	500g
White Rice (uncooked)	185g	0.54 cups	1.08 cups	1.35 cups	2.70 cups
Brown Rice (uncooked)	190g	0.53 cups	1.05 cups	1.32 cups	2.63 cups

Rice absorbs water as it cooks, so cooked rice weighs and measures very differently from the dry, uncooked amounts in this chart.

Sugar Conversion Chart

Sugar Type	Grams per Cup	100g	200g	250g	500g
Granulated Sugar	200g	0.50 cups	1.00 cup	1.25 cups	2.50 cups
Brown Sugar (packed)	220g	0.45 cups	0.91 cups	1.14 cups	2.27 cups
Brown Sugar (unpacked)	180g	0.56 cups	1.11 cups	1.39 cups	2.78 cups
Powdered Sugar	120g	0.83 cups	1.67 cups	2.08 cups	4.17 cups

Liquid Sweetener Conversion Chart

Sweetener	Grams per Cup	100g	200g	250g	500g
Honey	340g	0.29 cups	0.59 cups	0.74 cups	1.47 cups
Maple Syrup	322g	0.31 cups	0.62 cups	0.78 cups	1.55 cups
Molasses	340g	0.29 cups	0.59 cups	0.74 cups	1.47 cups
Corn Syrup	340g	0.29 cups	0.59 cups	0.74 cups	1.47 cups

Maple syrup is the lightest liquid sweetener per cup because it holds more water than honey, molasses, or corn syrup.

Grams to Cups for Flour

Flour causes more baking disasters than any other ingredient, and it's almost always a measuring problem, not a recipe problem.

Two ways to measure flour by cup:

• Spoon and level (recommended): Spoon flour into the cup until it's overfull, then level it off with a knife. This keeps the flour light and lands close to 125 grams per cup.
• Dip and sweep: Dip the cup straight into the flour bag and pull it out full. This packs the flour down and can push the weight up to 140+ grams per cup 15–20% more than spooning.

That gap explains why the exact same recipe can turn out dry for one baker and light and fluffy for another. They're using the same cup, but not the same amount of flour.

Sifted vs. unsifted: Sifted flour is aerated and lighter closer to 110 grams per cup. If a recipe says "flour, sifted," measure first, then sift. If it says "sifted flour," sift first, then measure. The order changes your result.

The simplest fix for all of this? Weigh your flour in grams. It skips the technique question entirely.

Grams to Cups for Sugar

Sugar seems simple, but three common types behave very differently in a measuring cup.

• Granulated sugar pours and settles evenly. 200 grams fills about 1 cup, no matter how you scoop it.
• Brown sugar should be packed firmly into the cup until it holds the cup's shape when turned out. Packed brown sugar is about 220 grams per cup. Loosely measured, that same cup might hold only 180 grams a 40-gram gap that changes moisture and sweetness in your bake.
• Powdered sugar is light and prone to clumping. Sift it before measuring if it's lumpy a lumpy cup traps air pockets and throws off the 120-gram-per-cup baseline.

For candy-making, caramel, and meringue, sugar accuracy isn't optional. A 20-gram miss can be the difference between a smooth caramel and a grainy one.

Why Grams Beat Cups Every Time

1. No scooping technique to get wrong. 100 grams is always 100 grams.
2. Consistent through humidity and settling. Flour that's settled in the bag still weighs the same.
3. Easy math for scaling. Doubling 250 grams is just 500 grams no fraction juggling.
4. One system works worldwide. A gram in Lahore is the same as a gram in London or Los Angeles.
5. Matches nutrition labels. If you're tracking calories or macros, weight-based measuring is already the standard.
6. It's the professional standard. Culinary schools and commercial bakeries measure by weight because it's repeatable, batch after batch.

Tips for Accurate Conversion

• Always check which ingredient you're converting before you trust a number.
• Use a digital kitchen scale that reads in 1-gram increments.
• Zero (tare) your scale between ingredients so leftover weight doesn't throw off your next measurement.
• Spoon light ingredients like flour and cocoa powder into the cup don't scoop straight from the bag.
• Pack brown sugar firmly unless your recipe says otherwise.
• Use a liquid measuring cup (with a pour spout) for liquids, and a dry measuring cup (filled to the brim, then leveled) for dry goods.
• When a recipe lists both grams and cups, trust the grams.

Common Mistakes to Avoid

• Treating every ingredient the same. A generic "1 cup = 240 grams" rule only works for water and a few similar liquids.
• Scooping flour straight from the bag. This packs it down and adds extra grams you didn't plan for.
• Mixing up US and metric cups. A metric cup (250 mL) is about 5% bigger than a US cup (236.6 mL) small on paper, but it adds up in a big batch recipe.
• Guessing the sugar type. "Sugar" in an older recipe usually means granulated, but check if the recipe mentions caramelizing or a moist texture first.
• Ignoring temperature. Cold butter and room-temperature butter pack into a cup differently, even at the same weight.
• Rounding too early. Round your final answer, not the numbers in the middle of your calculation.

Why Precise Measurements Matter in Baking

Baking is chemistry. Cooking is art add a little extra garlic and nothing bad happens. Baking doesn't forgive the same way.

Flour, fat, sugar, liquid, and leavening (baking soda or powder) all work together in a fixed ratio. Too much flour makes a cake dense and dry. Too little sugar changes browning, not just sweetness. Too much liquid can stop bread from holding its shape.

Weighing your ingredients removes the single biggest source of error in home baking: inconsistent cup-packing. That's why so many baking cookbooks especially ones translated from Europe list weights first and cups second, if cups are listed at all.

Grams to Cups in Popular Recipes

Here's how grams to cups conversion plays out in real recipes you might be baking this week.

Banana Bread

• 250g all-purpose flour = 2 cups
• 150g granulated sugar = ¾ cup
• 113g butter = ½ cup

Pancakes

• 180g all-purpose flour = about 1.4 cups (round to 1½ cups)
• 237g milk = 1 cup
• 50g granulated sugar = ¼ cup

Fudgy Brownies

• 100g cocoa powder = about 1⅛ cups
• 200g granulated sugar = 1 cup
• 227g butter = 1 cup

Homemade Pizza Dough

• 500g bread flour = about 3.9 cups
• 300g water = about 1¼ cups

Notice how the same ingredient flour, sugar, or butter always uses the same grams-per-cup value across every recipe. Once you know that number, you can convert any recipe that uses it.

FAQ’s

Can I Convert Any Ingredient From Grams to Cups?

Yes, as long as you know its density (grams per cup). This page covers the most common baking ingredients, but you can measure any ingredient's density yourself see "How to Calculate Ingredient Density" above. Weigh one level cup of it, and that number becomes your personal grams-per-cup value.

Why Do European Recipes Use Grams?

Most of the world uses the metric system, and grams are its standard weight unit. European bakers also value consistency weighing ingredients removes the guesswork that comes with cup sizes, scooping habits, and packing methods. Grams aren't "better," they're just the local standard outside the US.

Is 240g Always Equal to 1 Cup?

No. 240 grams only equals 1 cup for a small number of ingredients, mostly water and similar liquids. All-purpose flour is about 125 grams per cup, granulated sugar is about 200 grams per cup, and butter is about 227 grams per cup. The "240g = 1 cup" rule is a common myth that only holds true, by coincidence, for a few ingredients.

How Accurate Are Online Converters?

Accuracy depends on whether the converter asks for your specific ingredient. A converter using verified grams-per-cup data like the one on this page is generally accurate within a few percent, which is close enough for almost any home recipe. Be cautious of any tool or chart that gives you a single, universal number without asking what you're measuring.

Should I Pack Brown Sugar When Converting?

Yes, unless your recipe specifically says "loosely packed" or "unpacked." Packed brown sugar weighs about 220 grams per cup. The same cup, loosely filled, might hold only 180 grams a difference big enough to change your recipe's moisture and sweetness.

Can I Use the Same Conversion for Wet and Dry Ingredients?

No. Water weighs about 236 grams per cup, while all-purpose flour weighs about 125 grams per cup nearly double the difference. Oil, milk, honey, and syrup all have their own densities too. Always match your gram amount to the correct ingredient, whether it's wet or dry.

What If My Recipe Doesn't Specify the Ingredient Type?

Default to the most common version: all-purpose flour, granulated white sugar, or salted butter. If the recipe mentions caramelizing, a moist crumb, or a chewy texture, it may mean brown sugar instead. When in doubt, the gram measurement if one is listed is more reliable than guessing the ingredient type.

Do I Really Need a Kitchen Scale for Baking?

Not always, but it helps a lot. Cups work fine for casual, forgiving recipes like drop cookies or pancakes. For anything that depends on a precise ratio bread, cakes, macarons, pastry a scale removes most of the guesswork. A basic digital scale costs less than most kitchen gadgets and can pay for itself the first time it saves a recipe.

How Do I Convert 500 Grams to Cups?

Divide 500 by your ingredient's grams-per-cup value. For example: flour is 500 ÷ 125 = 4 cups, sugar is 500 ÷ 200 = 2.5 cups, and butter is 500 ÷ 227 = about 2.2 cups. Use the calculator above for instant results with any ingredient.

Why Do Different Websites Show Different Conversions?

Small differences usually come from three sources: which cup size the site assumes (US vs. metric), which measuring method it uses (spooned vs. packed), and which reference it pulled ingredient density from. A 5–10 gram difference per cup is normal between sites and won't meaningfully affect most recipes. If you need exact consistency, pick one source like this page and stick with it for a whole recipe.

Bonus: How Many Ounces Is ⅔ Cup?

For liquids, ⅔ cup equals about 5.3 fluid ounces (roughly 158 mL). For dry ingredients, the ounce weight depends on density: ⅔ cup of flour is about 2.9 oz (83g), while ⅔ cup of granulated sugar is about 4.7 oz (133g). Fluid ounces measure volume; regular ounces measure weight so always check which one your recipe means.

Conclusion

Grams to cups conversion isn't complicated once you remember one rule: the ingredient always comes first. A gram of flour, a gram of sugar, and a gram of honey all take up different amounts of space, so the ingredient decides your grams-per-cup number not a single universal formula.

Use the calculator at the top of this page for instant, ingredient-specific results. Keep the charts above bookmarked for quick reference while you cook. And if precision really matters for your recipe, remember that a $12 kitchen scale will always beat a measuring cup for consistency.

Whether you're converting 100 grams for a quick batch or 500 grams for a big one, you now have everything you need to get your grams to cups conversion right, every single time.
