About Cooking Conversions
Recipes from different countries use different measurement systems — US recipes typically use cups and tablespoons, European recipes use grams and milliliters, and UK recipes use yet another set of imperial measures. Converting between volume and weight requires knowing the density of the ingredient: a cup of flour and a cup of honey weigh very different amounts.
This tool ships with average densities for common baking and cooking ingredients. For maximum accuracy, weighing ingredients on a kitchen scale is always more precise than measuring volumes — flour in particular varies a lot depending on whether it's spooned, scooped, or sifted.
Frequently asked questions
US cups or metric cups?
This converter uses US cups (236.588 ml). Metric cups (250 ml) and Imperial cups (284 ml) differ — for those, multiply by 250/236.588 or 284/236.588 respectively.
Why doesn't 1 cup of flour equal 1 cup of water in grams?
Density differs by ingredient. A cup of water weighs ~237 g (1 g/ml). A cup of flour weighs only ~125 g because flour is full of air. That's why baking by weight is more reliable than by volume.
