Why One Cup of Flour Is Not One Cup of Sugar
A cup is a volume and a gram is a mass, so there is no single cups-to-grams number. Here is why flour is the…

In short
One us cup of butter is 227 gram. Going the other way, one gram is 0.0044052863 us cup. That works out at 2 us cup = 454 gram and 4 = 908. The figure comes from butter weighing 227 g per US cup — a generic cups-to-grams converter assumes water and will give you the wrong answer here, because volume to weight depends entirely on what is in the cup.

About the Cups to Grams — Butter
Butter is far easier to weigh than to measure by volume, and US recipes know it — a stick is a quarter pound, so half a cup, which is why they are printed with tablespoon marks on the wrapper. Cup measuring only makes sense for softened butter pressed into the cup with no air pockets. One US stick is 113 g, half a cup, or 8 tablespoons. European blocks are usually 250 g. The figure this page works from is 227 g per US cup, the spooned-and-levelled weight recorded by King Arthur Baking and the USDA food database. Converting us cup to gram for butter, the amounts that come up most often are: 1/4 us cup = 56.8 gram; 1/3 us cup = 75.7 gram; 1/2 us cup = 114 gram; 2/3 us cup = 151 gram; 3/4 us cup = 17 gram; 1 us cup = 227 gram; 1 1/2 us cup = 341 gram; 2 us cup = 454 gram; 3 us cup = 681 gram.
What people use it for
- Following a US recipe with a kitchen scale instead of cup measures.
- Scaling a recipe up or down without compounding measuring error.
- Converting a European recipe written in grams into cups.

The maths behind it
This tool uses gram = us cup × 227, derived from butter weighing 227 g per US cup. Every intermediate value is shown on screen, so the result can be checked by hand.
Butter is far easier to weigh than to measure by volume, and US recipes know it — a stick is a quarter pound, so half a cup, which is why they are printed with tablespoon marks on the wrapper. Cup measuring only makes sense for softened butter pressed into the cup with no air pockets.
Where this tool stops
Volume-to-weight conversion is inherently approximate. Humidity, brand, how finely something is milled and how long it has sat in the cupboard all shift the figure by a few per cent.
Explained in our guides
All guidesFrequently asked questions
How many sticks is a cup of butter?
Two. One stick is half a cup, 113 g, 8 tablespoons or 4 ounces. If you have a European 250 g block instead, a cup is a little under 91% of it — weighing is genuinely quicker than the arithmetic.
Why does a cup of butter not weigh the same as a cup of water?
Because a cup measures volume and a scale measures weight, and the two only agree for water. Butter has its own density — 227 g per US cup — so any generic volume converter gives the wrong answer here.
How much does the way I fill the cup matter?
Only if you insist on measuring it by volume, which is the harder path. Softened butter pressed into a cup with no air pockets gives the 227 g here; anything short of that traps air and under-measures. US sticks exist precisely to avoid this — one stick is half a cup, 113 g, printed on the wrapper.
Is a US cup the same as a UK or metric cup?
No. A US cup is 236.6 ml, a metric cup is 250 ml and an old UK cup is 284 ml. These pages use the US cup, because that is what US recipes mean.

Where does the Cups to Grams — Butter stop being reliable?
Volume-to-weight conversion is inherently approximate. Humidity, brand, how finely something is milled and how long it has sat in the cupboard all shift the figure by a few per cent. Knowing where a tool stops being trustworthy matters more than the cases where it works.
