Follow a US recipe without measuring cups
English-language recipes measure in cups and spoons; ours in grams. Since a cup’s weight depends on the ingredient, this tool applies the right density to give you reliable grams.
-
Choose the ingredient
Flour, sugar, butter, honey… each has its density.

With its unit: cup, spoon, oz, ml or g.

Plus the equivalent in cups and spoons.
A cup’s weight by ingredient
| Ingredient | 1 cup ≈ |
|---|---|
| Water | 237 g |
| Flour | 125 g |
| Sugar | 200 g |
| Butter | 227 g |
| Honey | 340 g |
Bases: 1 cup = 236.6 ml, 1 tbsp = 14.8 ml. Average values; packing changes the real weight.
Frequently asked questions
Why do I need to choose the ingredient?
Because the volume → weight conversion depends on density. 1 cup (≈ 237 ml) of flour weighs about 125 g, but 1 cup of sugar about 200 g and 1 cup of honey nearly 340 g. Without the ingredient, converting cups to grams is meaningless.
How much is a “cup” exactly?
The standard US cup is 236.6 ml. The tablespoon is 14.8 ml and the teaspoon 4.93 ml. Beware: the metric cup (250 ml) and the UK cup differ slightly.
Fluid ounce or weight ounce?
They are two different things. The fluid ounce (fl oz ≈ 29.57 ml) measures volume; the weight ounce (oz ≈ 28.35 g) measures mass. This tool distinguishes them: pick the unit that matches your recipe.
Are the values accurate to the gram?
They are good averages: real density varies with packing (sifted flour or not, brown sugar more or less compacted). For precision baking a scale is still ideal; these conversions get you close.
