Butter grams-to-cups conversion chart
All answers below use 227g of butter per US Customary cup, rounded to two decimal places.
| Butter weight | Approximate US cups |
|---|---|
| 25g | 0.11 |
| 50g | 0.22 |
| 75g | 0.33 |
| 100g | 0.44 |
| 113g | 0.5 |
| 125g | 0.55 |
| 150g | 0.66 |
| 170g | 0.75 |
| 200g | 0.88 |
| 225g | 0.99 |
| 227g | 1 |
| 250g | 1.1 |
| 300g | 1.32 |
| 400g | 1.76 |
| 500g | 2.2 |
These are decimal cups: 0.5 means ½ cup, and 0.75 means ¾ cup. A rounded answer is an estimate. For example, 113g rounds to 0.5 cup here, but exactly half of our 227g reference is 113.5g.

How many US sticks of butter are in a cup?
One standard US stick is ½ cup or 8 US tablespoons; two sticks make one cup. The wrapper often provides useful cutting marks, as shown in the Land O'Lakes guide linked above.
| US butter measure | US cups | US tablespoons |
|---|---|---|
| ½ stick | ¼ | 4 |
| 1 stick | ½ | 8 |
| 1½ sticks | ¾ | 12 |
| 2 sticks | 1 | 16 |
Check the package before using stick counts. This table refers to standard US sticks, not every block or package sold elsewhere.
How to convert butter grams to cups
Divide the butter weight by this page's reference:
US cups of butter = grams of butter ÷ 227
For example:
Calculate with the full reference and round only the final answer.
To go the other way, multiply US cups by 227: ¾ cup × 227 = 170.25g under this convention. Use the reverse toggle above or select butter in the cups-to-grams converter.
Why do some charts use 226g instead of 227g?
Rounding can explain the difference. King Arthur Baking's ingredient chart lists half a cup of butter as 4 ounces or 113g. Doubling that rounded gram value gives 226g.
Converting 8 ounces directly gives about 226.8g, which rounds to 227g, using NIST's ounce-to-gram conversion. Our calculator keeps 227g as its consistent full-cup reference. Neither rounded figure makes a cup measurement exact.
If a recipe specifies 225g, 226g or another weight, weigh that amount rather than changing it to match this chart.
Measuring butter for your recipe
With a scale: Place a bowl on the scale, zero it, and add the stated weight of butter. This avoids having to estimate an awkward fraction such as 0.44 cup.
With a marked wrapper: Use the cup or tablespoon marks for the amount requested. For an unmarked block or leftover pieces, weighing is more straightforward than estimating a fraction by eye.
When melting butter: If the recipe asks for a quantity of butter followed by “melted,” measure that quantity first, then melt it. If it explicitly requests a measured amount of already-melted butter, follow that instruction. This converter does not model changes in liquid volume with temperature.
Questions about converting butter
Does this work for whipped butter or butter spreads?
Do not assume those products have the same weight per cup as standard butter. Land O'Lakes advises measuring whipped butter by weight rather than volume. For spreads or blended products, follow the package and recipe guidance; this chart does not establish that they are suitable substitutes.
What about browned butter?
Use the weight and measuring stage specified by the recipe. King Arthur explains that browning butter evaporates water, so the starting weight and finished weight differ. Do not use this standard-butter conversion to predict the amount remaining after browning.
Does a 250mL metric cup give the same result?
No. Under our volume-scaling method, 100g of butter fills about 0.42 metric cups, compared with 0.44 US Customary cups. These are calculated estimates, not separate kitchen measurements. Choose the cup setting your recipe uses; the chart on this page stays in US cups. Our cup-size guide explains the standards, and our methodology explains the calculation.
