Volume belongs with volume

Cups, tablespoons, teaspoons and millilitres describe volume. In a US customary system, one cup contains 16 tablespoons or 48 teaspoons. Keep all the units in the same system when you use those relationships.

Weight belongs with weight

Grams, kilograms, ounces and pounds describe mass. These conversions do not depend on the ingredient. Fluid ounces describe volume and must not be substituted for ounces of mass.

Weight-to-volume needs an ingredient

A grams-to-cups table is only meaningful when it names the ingredient and its reference. Use the ingredient converter for this job, then return to this chart for unit relationships.

Practical rounding stays visible

Kitchen charts often use rounded values such as 5 ml for a teaspoon. Our exact unit calculations and practical kitchen approximations are labelled so you can see which kind of result you are using.

A few useful answers

Kitchen questions, answered.

Are US and UK fluid ounces equal?

No. A recipe using historical Imperial fluid ounces should not be read as US customary. The main interface provides US customary, metric and Australian settings; legacy Imperial volumes are not a visible option in this prototype.

Can I print this chart?

Use your browser’s Print option. The print layout removes navigation and keeps the chart and its measurement notes.

Why does a cup sometimes say 240 ml or 250 ml?

Different conventions exist. A rounded US kitchen reference can use 240 ml, while a metric cup is 250 ml. The calculator identifies its exact selected unit.
