Quick Reference Chart
These numbers assume 1 cup of flour equals 125 grams. For baking that needs to come out right every time, it's better to weigh your flour on a kitchen scale instead of scooping it into a cup.
| Flour (grams) | Cups |
|---|---|
| 50 g | ⅜ cup |
| 100 g | ¾ cup |
| 125 g | 1 cup |
| 150 g | 1¼ cups |
| 200 g | 1⅝ cups |
| 250 g | 2 cups |
| 300 g | 2⅜ cups |
| 500 g | 4 cups |
| 750 g | 6 cups |
| 1,000 g | 8 cups |
Getting an Accurate Cup Measurement
How you put flour into the cup changes how much it actually weighs. Follow these steps for a fairly reliable result:
- Stir or fluff the flour first so it isn't packed down.
- Spoon the flour into the measuring cup instead of scooping the cup through the bag.
- Don't press the flour down.
- Once the cup is full, run a knife or straight edge across the top to remove the extra.
This is often called the spoon-and-level technique, and it gives a more even, repeatable measurement than scooping.
Why the Method Matters
The same cup can hold a different amount of flour depending on how you fill it:
| Method | Weight per cup |
|---|---|
| Spoon in, then level off | 120–125 g |
| Scoop straight from the bag | 140 g or more |
| Sifted flour | 110–115 g |
Scooping the cup directly into the bag usually packs in more flour than you'd want. When a recipe's outcome really matters, weighing the flour is the safer bet.
Cup Weights for Different Flour Types
Flours aren't all the same density, so 1 cup doesn't weigh the same across types.
| Flour Type | Weight per Cup |
|---|---|
| All-purpose flour | 125 g |
| Bread flour | 127 g |
| Cake flour | 114 g |
| Whole wheat flour | 120 g |
| Almond flour | 96 g |
| Coconut flour | 128 g |
| Rye flour | 102 g |
| Self-rising flour | 125 g |
| Semolina | 167 g |
| Buckwheat flour | 120 g |
| Rolled oats | 104 g |
| Spelt flour | 120 g |
These figures are estimates — the exact weight can shift slightly depending on the brand, how much moisture is in the flour, how fine the particles are, and how you scoop it.

Converting Cups Back to Grams
If you already have an amount in cups and need grams instead, use this formula:
| Cups | Grams |
|---|---|
| ½ cup | 62.5 g |
| ¾ cup | 93.75 g |
| 1 cup | 125 g |
| 1½ cups | 187.5 g |
| 2 cups | 250 g |
| 3 cups | 375 g |
| 4 cups | 500 g |
Cup Sizes Around the World
Not every "cup" holds the same volume. This converter is built around the US customary cup, but here's how the sizes compare:
| Cup Standard | Volume |
|---|---|
| US customary cup | 236.6 mL |
| US legal cup | 240 mL |
| Metric cup | 250 mL |
| Imperial cup | 284.1 mL |
| Japanese cup | 200 mL |
If a recipe doesn't say which cup size it means, assume it's the standard US customary cup.
The Most Reliable Way to Measure Flour
Volume measurements can vary a lot depending on technique, so weighing flour on a kitchen scale is the most dependable method. If a recipe calls for 125 grams of flour, weighing that amount directly will give you better results than converting it to a cup measurement. When a scale isn't available, spoon the flour into the cup gently and level off the top rather than packing it down.
Does Sifting Affect the Weight?
Yes — sifting adds air into the flour, which lowers its density. A cup of sifted flour will weigh less than a cup of flour that hasn't been sifted. If a recipe specifically asks for "sifted flour," measure it after sifting, not before.
Other Ingredients
Grams-to-cups conversion isn't only useful for flour. The same idea applies to other kitchen staples, though each has its own weight-per-cup because densities differ:
