- Using the US kitchen standard (FDA and NIST): 1 cup = 240 ml, 1 fl oz = 30 ml. Switch to exact for the legal 236.6 ml cup — the difference is 1.4%.
- The cup row is the 250 ml metric cup used in Australia, New Zealand and Canada. Pints, quarts and gallons are US sizes — a UK pint is 568 ml.
- Converting between volume and weight (cups to grams) depends on the ingredient — use the cups to grams converter for that.
What is the Cooking Measurement Converter — Cups, Tbsp, ml, oz?
Recipes swap between teaspoons, cups, fluid ounces and millilitres without warning, and the US cup itself has two official sizes: the 240 ml cup the FDA uses on nutrition labels, and the 236.6 ml cup of exact US customary measure. This converter takes one amount and shows it in every unit of the same kind at once — all the volume measures for a liquid or spoonful, all the weights for anything you put on a scale. It uses the rounded 240 ml kitchen cup by default, like the rest of this site, and switches to exact customary or the 250 ml metric cup in one tap. Volume and weight are kept apart on purpose: turning cups into grams depends on the ingredient.

Frequently asked questions
Is a cup 240 ml or 236.6 ml? +
Both, depending on who is counting. Exact US customary measure makes a cup 236.6 ml (one-sixteenth of a 3.785 L gallon). The FDA rounds it to 240 ml for nutrition labels, along with 15 ml per tablespoon and 30 ml per fluid ounce, and most recipes follow that rounded set. The 1.4% gap never matters in cooking; the 250 ml metric cup is a bigger jump.
Is a fluid ounce the same as an ounce? +
No. A fluid ounce measures volume (about 30 ml) and an ounce measures weight (28.35 g). They only line up for water and liquids of similar density — a fluid ounce of honey weighs about 1.5 oz. Weigh dry ingredients, or use the cups to grams converter, which knows each ingredient’s density.
How accurate are the results? +
The figures come from standard, tested references (USDA FoodData Central and King Arthur Baking) and are excellent starting points. Ovens, ingredients and equipment vary, so treat the numbers as a reliable guide and adjust to taste and doneness.
Is this calculator free, and does it send my data anywhere? +
Yes — it’s completely free and runs entirely in your browser. Nothing you type is uploaded or stored on a server; the maths happens on your device, even offline once the page has loaded.
