How It Works

Volume measurements (cups, tablespoons) do not weigh the same for different ingredients. A cup of flour weighs much less than a cup of honey. Professional bakers use weight (grams) for accuracy.

The basic rule:

  • Each ingredient has a specific grams-per-cup value based on its density
  • 1 cup = 16 tablespoons = 48 teaspoons. Convert to cups first, then multiply by the ingredient's weight per cup.
  • Results also show ounces (grams ÷ 28.35) and milliliters for liquid ingredients

For best accuracy, use the spoon-and-level method for flour (spoon into cup, level with a knife) rather than scooping directly from the bag, which compacts the flour and adds up to 30% more weight.

Tips & Considerations

  • Double-check your amount before calculating — even small input errors can significantly change your results.
  • Run the calculator with different values to compare scenarios and find the optimal approach for your situation.
  • Pay attention to both grams and ounces — they work together to give you the full picture.
  • Bookmark this page for quick access next time you need to perfect your recipes.
  • If you're unsure about your ingredient, start with a conservative estimate and adjust from there.

Frequently Asked Questions

Why does a cup of flour weigh differently than a cup of sugar?

Ingredients have different densities. Flour is light and airy (120g/cup), while granulated sugar is denser (200g/cup) and honey is very dense (340g/cup). This is why weight-based recipes are more accurate than volume-based ones.

How many grams is one cup of all-purpose flour?

One cup of all-purpose flour is approximately 120 grams (4.25 oz) when measured using the spoon-and-level method. If you scoop flour directly from the bag, it can weigh 140-160 grams due to compaction.

Should I use weight or volume measurements for baking?

Weight (grams) is always more accurate for baking. A kitchen scale eliminates variability from how you scoop or pack ingredients. Most professional recipes and all European recipes use weight measurements.

How do I measure brown sugar in cups?

Brown sugar should be firmly packed into the measuring cup. Press it down with your fingers or the back of a spoon until level with the rim. One packed cup of brown sugar weighs about 213 grams (7.5 oz).

Are metric cups the same as US cups?

No. A US cup is 236.6 ml. A metric cup (used in Australia) is 250 ml. A UK/Imperial cup is 284 ml. This calculator uses US cups. If using metric cups, multiply grams by 1.057.

What is the most accurate way to measure ingredients?

Use a digital kitchen scale that reads in grams. Place your bowl on the scale, tare (zero) it, then add the ingredient. This eliminates measuring cup variability entirely and is the standard in professional baking.
