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 because the gram was originally defined as the mass of one millilitre of water.

Many recipes — particularly 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.
