100 grams of butter = 0.44 cups (½ cup / 7.0 tbsp / 21.1 tsp)
Butter has a density of approximately 227g per cup. Solid or melted weighs the same per cup. Source: USDA FoodData Central. This is the figure used everywhere on this page, including the tablespoon and teaspoon values, so the numbers stay consistent whether you're reading the summary line, the table, or the FAQ answers below.
| Grams | Cups | Fraction | Tablespoons | Teaspoons |
|---|---|---|---|---|
| 90g | 0.40 | ⅜ | 6.3 | 19.0 |
| 95g | 0.42 | ⅜ | 6.7 | 20.1 |
| 100g | 0.44 | ½ | 7.0 | 21.1 |
| 110g | 0.48 | ½ | 7.8 | 23.3 |
| 120g | 0.53 | ½ | 8.5 | 25.4 |
How the 100g Figure Is Calculated
100g divided by 227g (the weight of one cup of butter) equals 0.44 cups. Multiplying that by 16 gives 7.0 tablespoons, and by 48 gives 21.1 teaspoons, since one cup always equals 16 tablespoons or 48 teaspoons regardless of the ingredient.
Butter is lighter than water, which weighs about 236g per cup. That's why 100g of butter takes up more volume (104ml) than the same weight of water would (100ml). For a side-by-side look at how other ingredients compare, see the 100 grams to cups page.
If Your Recipe Uses Metric or Imperial Cups
The 0.44 cup figure above uses the US Customary cup (236.588ml). Recipes written outside the US sometimes use a metric cup (250ml) or an imperial (uk) cup (284.131ml) instead. At 100g, that's ⅜ metric cups or ⅜ imperial cups of butter, close to the US figure but not identical. The cup standard switch in the converter above recalculates this instantly for any gram amount.
Scaling 100g Up or Down
Doubling a recipe that calls for 100g of butter means weighing 200g, or measuring 0.88 cups if you're working by volume instead of weight. Halving it means 50g, or 0.22 cups. Weight scales exactly with simple multiplication; cup measurements compound any scooping error each time they're doubled or halved, so weighing is more reliable the more a recipe is scaled.
Butter vs. Other Fats & Oils
Within fats & oils, density still varies by ingredient. At 100g, vegetable oil (218g per cup) measures ½ cup, while olive oil (216g per cup) measures ½ cup, compared to ½ cup for butter. Swapping ingredients in a recipe by cup measurement alone, without adjusting for this difference, changes the actual weight used.
Where 100g of Butter Fits in a Recipe
- Most cookie recipes call for 227g (1 cup, or 2 sticks) of butter.
- A pound cake typically uses 227g to match its name.
- Pie crusts often need 113g (1 stick) per single crust.
How to Measure It Accurately
Fats & Oils
Press solid fats like butter into the cup to remove air pockets, then level the top. Liquid oils should be poured to the marked line at eye level.
For exact results
Room-temperature butter measures more consistently than cold butter, since cold butter can leave small gaps when pressed into a cup. For melted butter, measure the volume after melting, not before, since melting slightly changes how it fills a cup.
For every gram amount at once, the butter conversion chart lists butter across the full range from 1g to 1000g in one table.
Frequently Asked Questions
What is 100 grams of butter in cups?+
100 grams of butter is 0.44 cups (½ cup), or 7.0 tablespoons.
How do I measure 100 grams of butter without a scale?+
Use ½ cup, spooned in and leveled off with a straight edge. If you only have tablespoons, use 7.0 tablespoons instead.
Why is butter's gram-to-cup ratio different from other ingredients?+
Butter weighs 227g per cup because of its own density. Solid or melted weighs the same per cup.
Does a metric or imperial cup change this 100g conversion?+
Yes, slightly. 100g of butter is ⅜ metric cups or ⅜ imperial cups, versus ½ US cups, since each cup standard holds a different volume.
