Butter grams to cups
To convert grams to cups, divide the grams by 227. For example, 100 g of butter ≈ 0.44 cup.

Butter is one of the easiest ingredients to convert accurately, because US sticks are pre-portioned: one cup is 227g, which is exactly two sticks (or half a standard 454g block). The wrapper does most of the math for you.

Why butter weighs what it does
A cup of butter weighs 227g because it is almost pure fat with very little air, so it packs densely and consistently. The number barely shifts between brands, unlike flour or sugar. Where it does vary is European-style butter, which has a higher fat content (82-86% versus the US standard 80%) and slightly less water, so a cup can weigh a gram or two more. Temperature matters too: cold butter holds its shape, but whipped or very soft butter traps air, throwing volume measurements off while the weight stays honest.
How to measure butter
Skip the measuring cup entirely. US butter wrappers are printed with tablespoon and cup marks, so just slice at the line: one stick is 1/2 cup (113g), two sticks make a full cup. For blocks or European butter without markings, a scale is far faster and cleaner than packing soft butter into a cup and scraping it out.
Common mistake
Confusing a stick with a cup. A US stick is half a cup (113g), not a full cup, so reading "1 cup butter" as one stick halves your fat and wrecks the recipe. The other trap is packing soft butter into a cup with air pockets, which under-measures the actual weight.
Other cup sizes
| Cup type | 1 cup of butter |
|---|---|
| US cup (240 ml) | 227 g |
| Metric cup (250 ml) | 236 g |
| Australian / South African cup (250 ml) | 236 g |
| Imperial cup (284 ml) | 269 g |
Where it matters
Getting butter exact matters most in pastry and cookies, where the fat-to-flour ratio controls flakiness and spread. Shortcrust, croissants, pound cake, and shortbread are unforgiving of being off by even 20-30g. In sauces or for greasing pans, precision matters far less and the wrapper marks are plenty.
FAQ
How many sticks of butter are in one cup?
Two sticks. Each US stick is half a cup, or 113g, so two sticks give you a full cup at 227g.
Is European butter the same weight per cup?
Almost. European-style butter has more fat and less water, so a cup runs a gram or two heavier than the 227g US standard. The difference is negligible for most recipes.
Does it matter if the butter is melted or softened when I measure by weight?
No. Weight stays the same whether butter is cold, softened, or melted. Only volume measurements change, because soft or whipped butter traps air.
How do I measure butter without the printed wrapper marks?
Use a scale. Weigh out the grams you need directly. Packing soft butter into a measuring cup works but is messy and less accurate.
