150 grams to cups changes depending on what's on your kitchen scale. 150 grams is about 1.25 cups of flour, 0.75 cups of sugar, or 0.66 cups of butter three very different answers from the exact same weight.

Use the calculator above for an instant conversion across more than 50 ingredients. Below, you'll find a full ingredient breakdown, the formula behind every number, and how to handle ingredients like mashed fruit that don't have one fixed density at all.

How Many Cups Is 150 Grams? (Quick Answer)

Here's how 150 grams converts to cups for the ingredients people search for most:

Ingredient	150g in Cups
All-Purpose Flour	1.25 cups
Granulated Sugar	0.75 cups
Brown Sugar (Packed)	0.68 cups
Butter	0.66 cups
Powdered Sugar	1.25 cups
Rice (Uncooked)	0.81 cups
Oats (Rolled)	1.88 cups
Cocoa Powder	1.5 cups
Yogurt	0.61 cups

Oats and cocoa powder stand out here both are light, airy ingredients that spread across well over a cup at 150 grams, while butter barely clears half a cup at the same weight.

150 Grams to Cups by Ingredient

150 Grams of Flour to Cups

150 grams of all-purpose flour equals about 1.25 cups, based on the standard spoon-and-level measurement of 120 grams per cup. This is a full 1/4 cup more than the "1 cup" mark, so it's easy to underestimate if you're eyeballing it.

150 Grams of Sugar to Cups

150 grams of granulated sugar equals 0.75 cups, or exactly 3/4 cup a clean, easy-to-remember number. Brown sugar, being denser once packed, comes out slightly lower at about 0.68 cups for the same weight.

150 Grams of Butter to Cups

150 grams of butter equals about 0.66 cups, just under 2/3 cup. Since butter is a solid, uniform block, this conversion holds up consistently no matter how it's measured.

150 Grams of Brown Sugar to Cups

150 grams of packed brown sugar equals about 0.68 cups. Brown sugar is measured packed by convention if it's loosely spooned instead, the same weight will fill noticeably more volume.

150 Grams of Powdered Sugar to Cups

150 grams of powdered sugar equals about 1.25 cups, the same ratio as flour, since the two have very similar densities despite looking and behaving completely differently in a recipe.

150 Grams of Rice to Cups

150 grams of uncooked rice equals about 0.81 cups. As always, this is for uncooked rice cooked rice absorbs water and takes up noticeably more space per gram, so double-check which one your recipe means.

150 Grams of Oats to Cups

150 grams of rolled oats equals about 1.88 cups, nearly 2 full cups. Oats are one of the lightest common baking ingredients, with lots of air trapped between the flakes.

150 Grams of Yogurt to Cups

150 grams of plain yogurt equals about 0.61 cups, just over half a cup. This is one of the more predictable conversions on this page, since yogurt behaves like a thick liquid rather than a packable dry ingredient.

How to Convert 150 Grams to Cups (Formula)

Cups = Grams ÷ Grams-Per-Cup Value

Worked Example: 150 Grams of Sugar

1. Find the grams-per-cup value for sugar: 200 grams.
2. Divide: 150 ÷ 200 = 0.75.
3. Answer: 0.75 cups, or exactly 3/4 cup.

What About Ingredients With No Fixed Density?

Most conversions on this page are reliable because flour, sugar, and butter behave the same way every time. But some ingredients don't have one single "grams per cup" answer and it's worth knowing which ones.

Mashed banana is a good example. A ripe, very soft banana mashes down smoothly and packs tightly into a cup, while a firmer, less-ripe banana leaves more air pockets and takes up more space for the same weight. As a rough average, 150 grams of mashed banana is close to 0.67 cups but this can shift by 10–15% depending on ripeness and how finely it's mashed.

The same uncertainty applies to jams, purees, and anything with variable water content or chunk size. When you're converting one of these, treat the result as a solid estimate rather than an exact figure, and adjust to the recipe's texture as needed.

Why Does 150 Grams Fill a Different Amount of Every Cup?

The answer is always density how tightly an ingredient's particles pack together.

• Oats and cocoa powder trap a lot of air, so 150 grams fills well over a cup.
• Butter and yogurt are dense and uniform, so the same weight fills barely half a cup.
• Flour and powdered sugar sit in between, both landing around 1.25 cups.

Common Questions About 150 Grams
