Frequently Asked Questions

How many grams in a cup?
It depends on the ingredient. A cup of plain flour weighs about 125 grams, while a cup of sugar weighs about 200 grams. This is because different ingredients have different densities.
Are US cups and UK cups the same?
No. A US cup is 236.588 ml, while an Imperial (UK) cup is 284.131 ml. Most recipes online use US cups. The Kitchen Calculator uses US cups as the standard.
Why do cups to grams vary by ingredient?
Because cups measure volume, not weight. A cup of something light and fluffy (like flour) weighs less than a cup of something dense (like honey). This is why professional bakers prefer weighing ingredients.
Should I weigh or measure ingredients?
Weighing is always more accurate. But if you only have cups and spoons, our converter gives you reliable gram equivalents for each ingredient.
How many tablespoons in a cup?
There are 16 US tablespoons in 1 US cup. There are 48 US teaspoons in 1 US cup.
What's the best way to measure ingredients accurately?
The most accurate way is to use a digital kitchen scale. Weighing eliminates the variability of cup measurements — different measuring techniques can result in 20-30% differences. If you must use cups, use the spoon-and-level method: spoon the ingredient into the cup and level off with a knife. See our recommended tools →
