Food & Cooking Calculator

Cooking Unit Converter

Convert common cooking units such as teaspoons, tablespoons, cups, millilitres, litres, grams, kilograms, ounces and pounds. For cups-to-grams conversions, choose the ingredient so the estimate uses a sensible density.

Convert units Cups to grams note

Convert cooking units

Choose an amount, the unit you have and the unit you want. Weight-to-volume and volume-to-weight conversions use the selected ingredient, because a cup of flour does not weigh the same as a cup of sugar or milk.

AmountEnter the quantity you want to convert.

From unitThe unit in the recipe.

To unitThe unit you want.

Ingredient for cups ↔ gramsOnly needed when converting between volume and weight.

Custom densityGrams per ml. Plain flour is about 0.53 g/ml.

Decimal placesControls the main result rounding.

Converted amount127.2 gUsing plain flour density.

Kitchen rounded127 gUseful for everyday cooking.

Conversion typeVolume → weightDensity is used where needed.

This calculator treats 1 teaspoon as 5ml, 1 tablespoon as 15ml and 1 cup as 240ml. Cups-to-grams results are estimates because ingredients have different densities.

How the cooking unit converter works

For simple volume conversions, the calculator converts everything through millilitres. For simple weight conversions, it converts everything through grams.

volume conversions: amount × unit ml value
weight conversions: amount × unit gram value
volume to weight: millilitres × ingredient density
weight to volume: grams ÷ ingredient density

That means teaspoons to tablespoons are straightforward, but cups to grams need an ingredient choice.

Why cups to grams are not always exact

A cup is a volume measure. A gram is a weight measure. The same cup volume can weigh very differently depending on what is inside it, so a cup of flour, sugar, butter and milk should not all be treated as the same weight.

Flour: can vary depending on how tightly it is packed.
Sugar: usually weighs more per cup than flour.
Liquids: water and milk are close to 1g per ml.
Best practice: use grams for baking where precision matters.
