Pourquoi les conversions cuisine sont-elles compliquées ?

Because American recipes use "cups" (a volume measurement) while European recipes use grams (a weight measurement). The problem: 1 cup of flour ≠ 1 cup of sugar in weight, because these ingredients don't have the same density.

1 cup of flour ≈ 125 g, but 1 cup of sugar ≈ 200 g. That's why a simple ratio doesn't work — you have to know the density of each ingredient.

Les équivalences à connaître par cœur

A few basic conversions:

1 cup = 236 ml ≈ 240 ml (common rounding) 1 tbsp = 15 ml 1 tsp = 5 ml 1 oz = 28.35 g 1 lb = 453.6 g 1 fl oz = 29.6 ml

And the most useful densities: flour ~125 g/cup, sugar ~200 g/cup, butter ~227 g/cup, milk ~245 g/cup.

Cups, tablespoons, teaspoons : décryptage

The American system uses nested volumetric measurements: 1 cup = 16 tablespoons = 48 teaspoons. It's convenient because you don't need a scale — just measuring cups.

But be careful: American "cups" (236 ml) are different from British imperial cups (284 ml). This converter uses American cups, which are the standard in most online recipes.

Questions fréquentes

Pourquoi la conversion change selon l'ingrédient ?
Because every ingredient has a different density. Flour is light and airy (0.53 g/ml), honey is heavy and dense (1.42 g/ml). To convert volume ↔ weight, density is essential.
La conversion est-elle exacte ?
It's precise to within ±5% for common ingredients. Density can vary slightly based on brand, temperature, or how packed it is (packed flour weighs more than sifted flour).
Comment mesurer une « cup » sans gobelet doseur ?
Use this converter to get the weight in grams, then weigh it with a kitchen scale. It's more precise than any visual estimation. A kitchen scale costs less than $10 and is a game-changer for baking.
Les cuillères françaises et américaines font-elles la même taille ?
Practically. A French "cuillère à soupe" is ~15 ml (like a US tablespoon). A "cuillère à café" is ~5 ml (like a US teaspoon). The difference is negligible for cooking.
