Cooking Converter

Convert cooking measurements between cups, tablespoons, teaspoons, millilitres and fluid ounces, plus cups-to-grams for common ingredients.

US kitchen measures

1 cup = 16 tbsp = 48 tsp = 8 fl oz = 236.6 ml  ·  1 tbsp = 3 tsp = 14.8 ml  ·  1 tsp = 4.93 ml

Cups to grams by ingredient

Volume-to-weight depends on density — always match the ingredient:

Ingredient (1 US cup)Grams
All-purpose flour120 g
Granulated sugar200 g
Brown sugar (packed)220 g
Butter227 g
Rice (uncooked)185 g
Rolled oats90 g
Cocoa powder100 g
Honey340 g

Baker's tip

For baking, weight beats volume: "1 cup of flour" varies by up to 30% with how you fill the cup, which is enough to change a cake's texture. When a recipe gives grams, use grams; use the table above to convert older cup-based recipes.

Frequently asked questions

How many ml in a cup?
A US cup is 236.6 ml (recipes often round to 240 ml). A metric cup, used in Australia, is 250 ml. This converter uses US measures.
How many tablespoons in a cup?
16 US tablespoons = 1 US cup. And 3 teaspoons = 1 tablespoon, so a cup is 48 teaspoons.
How many grams is a cup of flour?
About 120 g for spooned-and-levelled all-purpose flour. Scooping directly with the cup compacts it and can pack in 150 g+ — which is why bakers prefer weighing.
Why do cups convert to different gram amounts for different ingredients?
Cups measure volume, grams measure weight, and ingredients have different densities: a cup of honey (340 g) weighs almost three times a cup of oats (90 g). Volume-to-weight conversion always depends on the ingredient.
