Water Measurement Converter
Use the tool below to convert water from the measurements in your recipe to the measurements that you need.
Water is the most fundamental ingredient in cooking and baking. Used to hydrate doughs and batters, cook pasta and grains, make stocks and sauces, and dissolve ingredients, it appears in almost every recipe in some form. One metric cup (250 ml) of water weighs exactly 250 grams or 8.82 ounces, a clean, round number since the gram was originally defined as the mass of one millilitre of water.
Many recipes, particularly those from the US, list water in cups or fluid ounces, while others use millilitres or grams. This page lets you convert water between grams, cups, millilitres, fluid ounces, and more so you can match any recipe with whatever measuring equipment you have.

Frequently Asked Questions
- Are water and H2O the same thing?
- Yes. H2O is another name for water, so they are the same ingredient and measure identically. A cup of water weighs 250 grams under either name, and every conversion on this page holds whichever name your recipe uses. Recipes swap the two freely, so you can follow either without changing quantities or weighing any differently.
- What is 0.25 cups of water in tablespoons?
- 0.25 cups of water is 4.17 tablespoons. This is the same for any ingredient, since cups and tablespoons are both volume units and do not depend on what you are measuring. One cup is about 16.67 tablespoons, so 0.5 cups is 8.33 tablespoons. Use the volume converter to switch between cups, tablespoons, teaspoons, and millilitres for any amount. Open the volume converter
- How much does a cup of water weigh?
- 1 cup of water in grams is 250 grams. The ratio is fixed, so 2 cups is 500 grams and half a cup is 125 grams. Weighing water by the cup is the most common way to measure it for baking. See the full cup to grams chart for water, or use the converter on this page for any other amount. 1 cup water in grams
