Cooking Converter (Cups, Grams, Tbsp)
Recipes mix volume (cups, tablespoons) and weight (grams, ounces), and a cup of flour does not weigh the same as a cup of sugar or honey. This cooking converter handles both: it converts between cups, tablespoons, teaspoons, millilitres, fluid ounces, grams, kilograms, ounces and pounds, using the ingredient’s density when you cross between volume and weight. It also lets you choose the measuring system, because a tablespoon is 15 ml in most places, about 14.8 ml in the US and 20 ml in Australia. For baking, weighing is more accurate than scooping.
How to use the cooking converter (cups, grams, tbsp)
- Enter the amount and choose the unit you have.
- Choose the unit you want and the ingredient — it matters only when you convert between volume and weight.
- Pick the measuring system your recipe uses: US, metric or Australian.
- For bread and cakes, treat the weight as a guide and weigh ingredients when you can.
Formula
Volume units convert through millilitres using the measuring system chosen (US cup 236.588 ml, tablespoon 14.787 ml, teaspoon 4.929 ml; metric cup 250 ml, tablespoon 15 ml, teaspoon 5 ml; Australia tablespoon 20 ml). Weight = volume × ingredient density (grams per ml). Dry ingredients use packed-cup weights consistent with the King Arthur Baking ingredient weight chart, for example about 120 g of all-purpose flour and 198 g of granulated sugar per US cup.
Worked examples
One cup of flour in grams
One US cup of all-purpose flour is about 120 grams.
Butter in tablespoons
Four tablespoons of butter is about 56.49 grams (a quarter of a US cup).
The same tablespoon, different countries
One tablespoon of water is 14.79 ml in the US, 15 ml in metric recipes and 20 ml in Australia.

Practice problems
Try these yourself first, then check your answer. The answers come from the calculator above.
- How many grams is 2 cups of granulated sugar (US cups)?
Show answer
2 cups of sugar in g: 396
Common mistakes to avoid
- Assuming a cup always weighs the same. Flour, sugar and honey differ widely.
- Scooping flour straight from the bag, which packs it and can add 20% or more.
- Mixing US cups with metric cups from UK or Australian recipes.
- Using ounces of weight for fluid ounces of volume.
- Treating converted weights as exact. Humidity and packing change them.
Frequently asked questions
How many grams are in a cup of flour?
About 120 g for all-purpose flour, when spooned and levelled, per the King Arthur chart. Packed flour weighs more.
How many ml in a cup?
A US cup is 236.6 ml; a metric cup is 250 ml.
How many teaspoons in a tablespoon?
Three in the US, UK and metric systems. In Australia a tablespoon is 20 ml, so four teaspoons.
How many tablespoons in a cup?
Sixteen US tablespoons make a US cup.
Should I weigh or measure by volume?
Weighing is more accurate, especially for baking.
