Cooking Measurement Converter

Convert cups, tablespoons, teaspoons, milliliters, grams and ounces with real ingredient densities — because a cup of flour does not weigh a cup of sugar.

American recipes measure by volume — cups, tablespoons, teaspoons — while most of the world (and every kitchen scale) works in grams and milliliters. Translating between the two is not a single multiplication: a cup of water weighs 240 g, but the same cup of flour weighs only about 127 g and a cup of honey around 341 g. This converter does the translation properly, using the density of the ingredient you pick.

Choose an ingredient, enter an amount and select the units. Same-kind conversions (cups to milliliters, ounces to grams) are computed directly from exact unit sizes: this tool uses the US customary cup of 240 ml, a 15 ml tablespoon, a 5 ml teaspoon and the avoirdupois ounce of 28.3495 g. Volume-to-weight and weight-to-volume conversions go through the ingredient's density in grams per milliliter, and the result line always tells you which density was applied.

The densities are typical values for loosely spooned household measures — the same assumptions most published conversion charts use. Real-world flour can vary by 10–20% depending on how firmly it is packed, sifted or scooped, which is exactly why serious baking recipes give weights. Use the converter to translate a recipe, then trust your scale for precision work.

Everything runs locally in your browser: no server calls, no sign-up, and it keeps working offline once the page has loaded. Convert a vintage recipe's cups into grams, scale a European recipe back into US measures, or figure out how many tablespoons of butter replace 50 g — then copy the result with one click.
