How many grams are in a cup?

It depends entirely on the ingredient. A cup of all-purpose flour is about 125 grams, granulated sugar 200, butter 227 and honey 340. That is why any chart offering a single cups-to-grams number is only correct for one ingredient.

Why do bakers weigh ingredients instead of using cups?

Because a cup measures volume and how much flour fits in one depends on how it was filled. Scooping compacts it, spooning does not, and the difference can run to 15% — enough to change the texture of a cake. Weight removes that variable.

How many tablespoons are in a cup?

Sixteen tablespoons, or forty-eight teaspoons, in a US cup. Those are exact ratios that hold for any ingredient, since they are all volume measures.

What is 350°F in Celsius and gas mark?

350°F is about 177°C, which is gas mark 4 and the most common baking temperature in recipes. For a fan or convection oven, drop it by roughly 20°C.

About Cooking Measurement Converter

Cooking Measurement Converter handles the conversion most kitchen charts get wrong. Volume to volume is a fixed ratio — a cup is always sixteen tablespoons. Volume to weight is not: a cup of flour weighs about 125 grams and a cup of honey 340, so crossing between the two families needs to know what is in the cup. Pick from eighteen common baking and pantry ingredients and the density is applied automatically. Fractions typed the way recipes are written — 1/2, 3/4, 1 1/2 — are understood directly. An oven section converts Fahrenheit to Celsius, gives the fan-oven equivalent and the matching UK gas mark.

Example

Input

1 1/2 cups of all-purpose flour to grams

Output

187.5 g

Flour is about 125 g per cup, which is why weighing gives far more consistent baking than scooping.

Common errors & troubleshooting

The converter will not turn cups into grams. — Pick an ingredient first. Volume and weight only relate through density, so without knowing whether the cup holds flour or honey the conversion has no single answer.
The gram figure does not match the one on a packet. — Densities vary with how the ingredient is handled. Scooped flour can weigh 15% more than spooned and levelled flour, which is precisely the inconsistency that weighing eliminates.
A recipe's cup measurement gives odd results. — Check which cup the recipe means. This tool uses the US cup of 236.6 ml; a metric cup is 250 ml and an imperial cup 284 ml, so an Australian or older British recipe will differ.
The amount field rejects what you typed. — Use a decimal like 2.5, a simple fraction like 3/4, or a mixed number like 1 1/2. Ranges and words such as "a pinch" cannot be converted.
