Butter Sticks Conversion Chart
These amounts are for US butter sticks. Butter sold outside the US often comes in other package sizes, so check the label before you convert. Stick weights follow the 4 oz (¼ lb) package label, so they may differ by about 1g from the cup-based amounts above.
| Sticks | Grams | US cups | tbspTablespoons |
|---|---|---|---|
| ½ | 57g | ¼ | 4 |
| 1 | 113g | ½ | 8 |
| 1½ | 170g | ¾ | 12 |
| 2 | 227g | 1 | 16 |
| 3 | 340g | 1½ | 24 |
| 4 | 454g | 2 | 32 |
Using a 250g Butter Block?
One US butter stick weighs approximately 113g, so it is about 45% of a 250g block. Use a kitchen scale for the most accurate portion.
Common Butter Measurements in Recipes
Not sure how much butter to use? These common recipe measurements show the equivalent amounts in grams and how to measure them from a 250g block.
1 stick butter
Recipe calls for: 1 stick butter
Use: about 113g
Equivalent to ½ US cup or 8 tablespoons.
Practical tip: Cut about 45% of a 250g butter block — slightly less than half.
¾ cup butter
Recipe calls for: ¾ cup butter
Use: about 170g
Equivalent to 1½ US sticks or 12 tablespoons.
Practical tip: Use about 68% of a 250g butter block — a little more than two-thirds.
200g butter
Recipe calls for: 200g butter
Equivalent to: about 0.88 US cups
Approximately 14.10 tablespoons.
Practical tip: Use 80% of a 250g butter block, leaving about 50g.
These cutting proportions are approximate. For precise baking, weigh the butter instead of relying on visual estimates.
Sources & how they compare

|---|---|---|---|---|---|---|
| USDA FoodData Central — Butter, salted (FDC 173410) FDC ID: 173410 Backup copy: nutritionvalue.org | 227 g per 1 cup (volume not stated) | 227g | Direct | not specified | Adopted | 2026-08-04 |

Measuring step this site recommends: packed into cup.
When sources disagree, follow your recipe: use its gram weights if it gives them, or measure the way its author did. The adopted value is one stated convention, not a correction of the other sources.
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.
Common mistakes
- Assuming 1 cup of butter equals 240g like water — it is actually 227g per US cup.
- Swapping butter for the same number of cups of oil, which weighs less per cup.

Frequently asked questions
How many cups is 100 grams of butter?
100 grams of butter is about 0.44 cups, based on 1 US cup (240 ml) = 227g.
How many grams are in 1 cup of butter?
1 US cup of softened butter weighs about 227 grams when packed into the 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?
Soften the butter and pack it into the cup. 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 denser or lighter ingredient weighs a different amount per cup.
