Sources & how they compare
| Source | Reported value | Comparable source-cup value | Type | Measurement method | Adopted here | Checked |
|---|---|---|---|---|---|---|
| USDA FoodData Central — Butter, salted (FDC 173410)FDC ID: 173410Backup mirror reference: nutritionvalue.org mirror (backup reference) | 227 g/1 source cup (exact volume unknown) | 227g | Direct | not specified | Adopted | 2026-08-04 |

A comparable source-cup value only scales a half-cup or tablespoon serving to one source cup. When a source does not state the cup's exact volume, we do not present it as a fixed-milliliter normalization.
Measurement notes
- Butter is often sold in sticks in the US, and one stick equals 113g (about half a cup).
- Soft butter should be packed firmly into the measuring cup to avoid air pockets that skew the weight.
- Cold butter is harder to measure accurately by volume — let it soften to room temperature first.
- European-style butter has a slightly higher fat content, which can make it marginally denser than US butter.
Common mistakes
- Not measuring butter the recommended way — packed into cup — is one of the most common sources of error.
- Assuming 1 cup of butter equals 240g like water — it is actually 227g per US cup.
- Measuring cold, hard butter by volume instead of letting it soften first.

How many grams are in 1 cup of butter?
1 US cup of butter is about 227 grams, measured packed into cup.
Does 1 cup of butter weigh the same in a metric cup?
No. A metric cup (250 ml) holds slightly more than a US cup (240 ml), so 1 metric cup of butter is about 236.5g, compared with 227g in a US cup.
What's the best way to measure butter accurately?
For the most accurate result, packed into cup, and use a kitchen scale when your recipe calls for a precise weight.
Can I convert cups of butter back to grams?
Yes, use the Cups to Grams tool with butter selected to convert any cup amount back into grams.
Why does butter convert differently from other ingredients?
Grams measure weight and cups measure volume, so the conversion depends on how dense butter is. A cup of butter weighs 227g, while a denser or lighter ingredient weighs a different amount per cup.
