Cooking measurement converter

Turn cups into grams, grams into spoons and ounces into millilitres for the ingredient you are using. Flour, sugar and butter weigh very different amounts per cup, so pick the ingredient first.

How to use

Choose the ingredient, type the amount and pick the unit from your recipe. Every other unit is listed below at once, so you can read off grams, spoons or cups without switching anything.

Cups to grams: choose "All-purpose flour", enter 2 and select "Cup". You get about 250 g, which you can weigh on a kitchen scale.
Grams to cups: choose "Granulated sugar", enter 100 and select "Gram". You see how many cups, tablespoons and teaspoons that is.
Liquids: for water, milk and oil, millilitres and grams are almost the same, so you can switch freely between a measuring jug and a scale.

For baking, weighing with a scale is always more accurate than measuring by volume.

Frequently asked questions

How many grams is 1 cup of flour?

One US cup of all-purpose flour weighs about 125 g when spooned into the cup and levelled. If you scoop it straight from the bag it can be closer to 140 g, which is why baking recipes often give grams.

Why does a cup of sugar weigh more than a cup of flour?

Every ingredient has a different density. Sugar crystals pack tightly, so a cup weighs about 200 g, while light, airy flour weighs about 125 g. That is why you need to choose the ingredient before converting.

Is a cup the same size everywhere?

No. A US cup is about 237 ml, the metric cup used in Australia, Canada and much of Europe is 250 ml, and a Turkish water glass is around 200 ml. Check where your recipe comes from and choose the matching cup.

How many ml is a tablespoon and a teaspoon?

A tablespoon is 15 ml and a teaspoon is 5 ml, so three teaspoons make one tablespoon. Spoons should be level, not heaped, unless the recipe says otherwise.

How accurate are the results?

The weights are averages from common kitchen references. Depending on how firmly an ingredient is packed or how fine it is, the real weight can differ by around 10%. For everyday cooking that is fine; for delicate baking use a scale.
