Volume-to-volume conversions are exact for the standard you pick. Volume-to-weight needs a density, so the ingredient list stores the published weight of one US customary cup and divides by 236.588 mL. Dry ingredients are the awkward ones: a cup of flour can weigh anywhere from 120 g spooned and levelled to 150 g scooped straight from the bag, which is exactly why bakers weigh. Australian recipes use a 20 mL tablespoon rather than 15 mL — worth checking before you measure baking powder.

What is the Cooking Measurement Converter?

The ByteTools Cooking Measurement Converter handles the conversion recipes actually break on: volume to weight.

  • Twelve units of volume and weight converted in one view
  • US customary, US legal, metric and imperial cup and spoon sizes
  • Sixteen ingredients with published weights per cup, all editable
  • Density shown in g/mL so you can sanity-check any conversion
  • Copy the full equivalents list to the clipboard in one click
  • Runs entirely in your browser — no signup, nothing uploaded

How to use the Cooking Measurement Converter

  1. 1

    Enter the amount you have and choose the unit it is measured in.

  2. 2

    Pick the cup and spoon standard the recipe uses — US customary is the usual assumption for American recipes.

  3. 3

    Choose the ingredient so the tool has a density; edit the grams-per-cup box if your source states a different weight.

  4. 4

    Read the volume in millilitres, the weight in grams and the density in the three summary tiles.

  5. 5

    Scan the equivalents grid for every other unit, and use Copy all to paste the whole list.

About the Cooking Measurement Converter

The ByteTools Cooking Measurement Converter handles the conversion recipes actually break on: volume to weight. Enter an amount in any unit, choose the ingredient, and it shows the equivalent in cups, tablespoons, teaspoons, fluid ounces, millilitres, litres, pints, quarts, grams, kilograms, ounces and pounds all at once.

It knows that a cup is not one thing. Switch between the US customary cup of 236.6 mL, the US legal cup of 240 mL used on nutrition labels, the 250 mL metric cup and the 284.1 mL imperial cup, and every volume result changes accordingly. Sixteen ingredients carry a published weight per cup, and that weight is editable so you can match your own scale.

Nothing is uploaded — all the arithmetic happens in your browser. Dry ingredients are inherently imprecise by volume: a cup of flour ranges from about 120 g spooned and levelled to 150 g scooped from the bag, which is the whole reason serious bakers weigh instead.

Frequently asked questions

How many grams are in a cup of flour?

About 120 grams for all-purpose flour spooned into the cup and levelled off, which is the figure used here. Scooping straight from the bag compacts it and can push the same cup to 145 or 150 grams — a difference big enough to change a cake.

Is a US cup the same as a metric cup?

No. A US customary cup is 236.6 mL, the US legal cup used on nutrition labels is 240 mL, the metric cup is 250 mL and the imperial cup is 284.1 mL. That is up to a 20 per cent difference, which is why the standard selector matters.

How many tablespoons are in a cup?

Sixteen tablespoons make a US cup, and three teaspoons make a tablespoon. Note that Australian recipes use a 20 mL tablespoon rather than 15 mL, so an Australian tablespoon of baking powder is a third more than an American one.

Why do cups convert differently for different ingredients?

Because a cup measures volume and grams measure weight, so you need the ingredient's density. A cup of honey weighs 340 grams while a cup of cocoa powder weighs 85 — the same space, four times the mass. That is why the ingredient selector is required for any volume-to-weight conversion.

How many ounces are in a cup?

Eight US fluid ounces make a US customary cup, but that is a volume measure. A cup of an ingredient weighs eight ounces only if its density happens to be that of water — a cup of flour weighs about 4.2 ounces, so never assume fluid ounces and weight ounces are interchangeable.

Should I weigh or measure ingredients for baking?

Weigh, whenever a recipe gives you the option. Scales remove the packing, scooping and settling variation that makes cup measurements of flour and brown sugar swing by 20 per cent or more, and they leave you with fewer things to wash.
