Cooking Measurement Converter
Cups to grams for the ingredients that actually matter, plus volume, weight, and oven temperature conversion — all in one place.
Ingredient Converter
Volume-to-weight conversion — because a cup of flour and a cup of honey don't weigh the same.
1 cup = 120 g
Volume & Weight Converter
Plain unit conversion — no ingredient needed.
1 cup = 16 tbsp
Oven Temperature Converter
Fahrenheit, Celsius, and the nearest UK gas mark.

Why Weight Beats Volume for Baking
A cup is a unit of volume, but ingredients don't all pack the same way. A cup of flour, scooped and shaken loose, weighs less than the same cup pressed down — which is exactly why 1 cup of flour can range anywhere from 115g to 140g depending on how it was measured. Weighing ingredients on a kitchen scale removes that guesswork entirely, which is why most professional bakers measure by weight rather than volume.

Frequently Asked Questions
Why isn't 1 cup always the same weight?
Cups measure volume, not weight, and ingredients pack differently — a cup of flour (light, airy) weighs far less than a cup of honey (dense, no air pockets). That's why recipes that care about precision (mainly baking) are often written in grams instead of cups.
Is a US cup the same as a UK or metric cup?
No. A US cup is 236.588 mL, while a metric cup (used in the UK, Australia, and elsewhere) is exactly 250 mL — about a 6% difference. This converter uses US cup measurements, the standard in US recipes.
What's a reliable way to measure flour by volume if I don't have a scale?
Spoon the flour into the measuring cup and level it off with a knife, rather than scooping directly with the cup — scooping compacts the flour and can add 20-30% extra, which is a common cause of dense baked goods.
What temperature is gas mark 4 in Fahrenheit and Celsius?
Gas mark 4 is 350°F / 180°C, one of the most common baking temperatures.
