Why are kitchen conversions so complicated?

Because US 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 terms of weight, because these ingredients have different densities.

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

Equivalencies to know by heart

A few basic conversions:

1 cup = 236 ml ≈ 240 ml (common rounding) 1 tbsp (tablespoon) = 15 ml 1 tsp (teaspoon) = 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: decoded

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

But watch out: US "cups" (236 ml) are different from British Imperial cups (284 ml). This converter uses US cups, which are the standard in most online recipes.

Questions fréquentes

Why does the conversion change based on the ingredient?
Because every ingredient has a different density. Flour is light and airy (0.53 g/ml), while honey is heavy and dense (1.42 g/ml). To convert volume ↔ weight, density is essential.
Is the conversion exact?
It is accurate within ±5% for common ingredients. Density can vary slightly depending on the brand, temperature, or how it's packed (packed flour weighs more than sifted flour).
How can I measure a "cup" without a measuring cup?
Use this converter to get the weight in grams, then use a kitchen scale. It's more accurate than any visual estimation. A kitchen scale costs less than $10 and is a game-changer for baking.
Are French and US spoons the same size?
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.
