How to Use the Cooking Measurement Converter
Recipes often list ingredient amounts by volume — "1 cup," "1 tablespoon" — but cup sizes differ between countries and each ingredient has its own density, which makes converting to an exact weight (grams) tricky. This matters especially when following an international recipe: a US cup (240mL) is not the same as South Korea's standard measuring cup (200mL), so using them interchangeably can throw off your proportions.
This converter takes an amount in cups, tablespoons, teaspoons, or mL and applies the selected ingredient's density to show both volume (mL) and weight (grams) at once. Water-like ingredients with a density near 1 have almost identical volume and weight, but ingredients like flour (about 0.53g/mL) or honey (about 1.42g/mL) can differ substantially, making weight hard to guess from volume alone.
For baking, where precise measurement matters most, weighing ingredients on a scale is far more accurate than measuring by volume. Rather than assuming a foreign recipe's "cup" matches your own measuring cup, use this converter to check the actual mL and grams before you start cooking.
Frequently Asked Questions
A US cup is treated as 240mL for recipe conversion (the exact legal cup is 236.59mL). This differs from South Korea's standard measuring cup, which is 200mL, so watch out when following recipes from other countries.
All-purpose flour has a lower density than water, so a 240mL cup weighs about 127g (density ≈ 0.53g/mL). Weight per cup varies a lot depending on the ingredient.
A tablespoon is 15mL and a teaspoon is 5mL — these are standard across most US and international recipes.
