How to convert US butter sticks to cups

This calculation crosses from mass to volume, so it needs an ingredient reference. The calculator starts with butter at 226.7962 grams per US reference cup (us packaged butter; two 4 oz sticks per us cup. do not substitute melted for solid butter unless the recipe permits.). Choose the exact ingredient and form your recipe means before using the answer.

For a weight input, convert to grams, divide by the ingredient's grams per reference cup, then adjust for the selected cup or spoon volume. For a volume input, reverse the process. The answer is a recipe equivalent, not a laboratory density measurement, so brand, moisture, packing and measuring technique can all change the practical result.

Choose the measurement your recipe means

The default cup is US customary at 236.5882365 ml. Metric and Australian cups use 250 ml. A metric tablespoon is 15 ml; an Australian tablespoon is 20 ml. Fluid ounces, pints, quarts and gallons in this interface stay US liquid units whichever cup system you select.

For dry ingredients, check whether the recipe asks for a packed, sifted, chopped or level measure. Use the same preparation as the reference, and prefer the recipe author's gram quantities when they are given.

A few useful answers

Kitchen questions, answered.

Do I need to choose an ingredient?

Yes. Weight and volume connect through the ingredient's reference weight. A cup of flour and a cup of sugar have different masses, so the converter never assumes one universal value.

Can I enter a fraction?

Yes. Enter a decimal such as 0.5, a fraction such as 1/2, a mixed fraction such as 1 1/2, or a Unicode fraction such as ½. Blank, negative and zero-denominator inputs are rejected with a message.

Why does switching the cup system change the result?

US customary cups hold 236.5882365 ml. Metric and Australian cups hold 250 ml. The same amount therefore occupies a different number of cups, and Australian tablespoons (20 ml) differ from metric ones (15 ml).
