150 grams of flour to cups lands on a clean, easy-to-remember number: 1.25 cups, or exactly 1 1/4 cups, for standard all-purpose flour. It's one of the tidier conversions in baking, which makes it a useful reference point even when you're estimating other amounts.
Use the calculator above to convert 150 grams of flouror any amount instantly with our Grams to Cups converter. Below, you'll find the full breakdown, the correct measuring method, and a flour weight chart covering the most common types.
How Many Cups Is 150 Grams of Flour?
150 grams of all-purpose flour equals 1.25 cups, based on the standard spoon-and-level measurement of 120 grams per cup. This is one of the cleaner conversions on this page a full cup plus an extra quarter cup, with no awkward decimals to round.
Does 150g of Flour Equal 1 1/4 Cups?
Yes this is one of the few flour conversions that lines up exactly. 150 grams divided by 120 grams per cup comes out to precisely 1.25 cups, which is the same as 1 1/4 cups. No rounding needed.
Is 150 Grams of Flour Equal to 1 Cup?
No. 150 grams is noticeably more than 1 cup it's 1.25 cups, a full quarter cup extra. A level cup of all-purpose flour weighs about 120 grams, so 150 grams is 30 grams (about a quarter cup) heavier than a single cup.
How Much Does 1 Cup of Flour Weigh?
A single level cup of all-purpose flour, measured with the spoon-and-level method, weighs about 120 grams. This is the baseline figure behind every conversion on this page multiply it by the number of cups, or divide a gram amount by it, to convert in either direction.
The Spoon-and-Level Flour Method
Almost every flour conversion chart, including this one, assumes flour was measured using the spoon-and-level method the industry standard among professional bakers and recipe developers:
- Fluff the flour in its container to loosen any settling.
- Spoon it into the measuring cup loosely, without packing it down.
- Level the top with the flat edge of a knife, removing the excess.
Skipping this method by scooping the cup directly into the bag, for example packs the flour down and can add 10–20% more weight to the same "1 cup" measurement, which is one of the most common sources of baking measurement errors.
Sifted vs. Unsifted Flour: Does It Change 150 Grams?
Here's a detail that trips up a lot of home bakers. The same 150 grams of flour can measure differently in cups depending on whether it's sifted:
- "150g flour, sifted" (measure first, then sift): still close to 1.25 cups.
- "150g sifted flour" (sift first, then measure): sifting adds air, so this can measure noticeably more sometimes 10–15% more volume for the same weight.
If a recipe's texture seems off despite following the gram measurement exactly, check whether the sifting instruction was meant to happen before or after measuring.
150 Grams of Self-Rising Flour to Cups
Self-rising flour includes baking powder and salt already mixed in, which makes it slightly denser than plain all-purpose flour typically around 125 grams per cup instead of 120. Converting 150 grams of self-rising flour gives you about 1.20 cups, a touch less than the 1.25 cups you'd get with standard all-purpose flour.
150 Grams of Flour to Cups by Flour Type (Weight Chart)
Different flour types pack differently into a cup, which shifts the exact conversion:
| Flour Type | Grams per Cup | 150g in Cups |
| All-Purpose Flour | 120g | 1.25 cups |
| Self-Rising Flour | ≈125g | 1.20 cups |
| Bread Flour | 127g | 1.18 cups |
| Cake Flour | 114g | 1.32 cups |
| Almond Flour | 96g | 1.56 cups |
Almond flour needs well over a cup and a half to reach 150 grams, while denser bread flour needs slightly less than a cup and a quarter all from the same starting weight.
How to Convert 150 Grams of Flour to Cups (Formula)
Cups = Grams ÷ Grams-Per-Cup Value
Worked Example
- Find the grams-per-cup value for all-purpose flour: 120 grams.
- Divide: 150 ÷ 120 = 1.25.
- Answer: 1.25 cups, or exactly 1 1/4 cups.
This same formula works as a general flour grams-to-cups calculator for any flour type just swap in the correct grams-per-cup value from the chart above.
FAQ’s
How many cups is 150 grams of flour?
150 grams of all-purpose flour is exactly 1.25 cups, or 1 1/4 cups, based on the standard spoon-and-level measurement of 120 grams per cup.

No. 150 grams is more than 1 cup it's 1.25 cups, a quarter cup more than a single level cup of flour.
How much does 1 cup of flour weigh?
A level cup of all-purpose flour, measured with the spoon-and-level method, weighs about 120 grams. This figure is the basis for every conversion on this page.
How many cups is 150 grams of self-rising flour?
150 grams of self-rising flour is about 1.20 cups, slightly less than all-purpose flour's 1.25 cups, since self-rising flour is a bit denser due to the added baking powder and salt.

150 grams happens to be exactly 1.25 times the standard 120-gram cup weight for all-purpose flour, which is why it converts to a clean 1 1/4 cups with no rounding needed one of the tidiest gram-to-cup conversions in baking.
What's the most accurate way to measure 150 grams of flour?
A digital kitchen scale is the most accurate method, since it removes any guesswork from spooning, leveling, sifting, or ingredient density. If you don't have one, the spoon-and-level method described above gets you very close.
