Grams to Cups Converter
Quickly convert grams to cups for flour, sugar, butter, and 15+ other common ingredients. Stop guessing and get your baking measurements perfectly accurate.
Formula
cups = grams ÷ 125g
(All-purpose flour: 125g per cup)
Quick Reference — All-purpose flour
| Grams | Cups | Decimal |
|---|---|---|
| 50g | ⅜ | 0.40 |
| 100g | ¾ | 0.80 |
| 150g | 1 ¼ | 1.20 |
| 200g | 1 ⅝ | 1.60 |
| 250g | 2 | 2.00 |
| 300g | 2 ⅜ | 2.40 |
| 500g | 4 | 4.00 |
Note: Cup measurements vary by ingredient density. Always use a kitchen scale for precise baking results.
Convert Grams to Cups for Real Baking Ingredients
British recipes give weights, American recipes give cups, and somewhere in the middle you have to convert. This converter handles 15 common baking ingredients with their actual densities: 1 cup of plain flour is 125g, 1 cup of granulated sugar is 200g, 1 cup of brown sugar packed is 220g, 1 cup of butter is 227g, 1 cup of honey is 340g. Pick the ingredient, type the grams, and get cups expressed both as a tidy fraction (¾, 1 ½) and an exact decimal.
The fraction display matters for practical baking. A US cup measure is marked at quarters and thirds; reading 'three quarters of a cup' off the converter is more useful than reading '0.83 cups' and trying to eyeball it. The decimal is shown underneath for when you need precision (small quantities of cocoa, baking powder).
Why the Same 100g Gives Different Cup Counts
100g of flour is 0.8 cups. 100g of sugar is 0.5 cups. 100g of honey is 0.29 cups. The reason is density: flour is light and fluffy, sugar is denser, honey is denser still. A cup is 240ml of volume, so heavier ingredients fit more grams into the same cup. This is exactly why baking by weight is more accurate than baking by cups; you remove the variable entirely.
If you are converting because the recipe is American and your scales are buried, use the converter and bake without worrying. If you are converting because you genuinely prefer cup measures, fine. If you are converting because a fussy bake (macarons, choux, sourdough) requires precision, weigh it. The [cups to grams converter](/cups-to-grams) is the reverse direction for when an American recipe gives cups and you want to weigh.
Common Grams to Cups Conversions
| Grams | Plain flour | Sugar | Butter | Honey |
|---|---|---|---|---|
| 50g | ⅖ | ¼ | ¼ | ⅛ |
| 100g | ⅘ | ½ | ½ | ⅓ |
| 150g | 1 ¼ | ¾ | ⅔ | ½ |
| 200g | 1 ⅗ | 1 | ⅞ | ⅔ |
| 250g | 2 | 1 ¼ | 1 ⅛ | ¾ |
| 500g | 4 | 2 ½ | 2 ¼ | 1 ½ |
Frequently Asked Questions
How many cups is 200g of flour?
200g of plain flour is approximately 1 ⅗ cups, or 1.6 cups. Bread flour is slightly denser at around 1 ½ cups for 200g. Cake flour is lighter at around 1 ¾ cups. Always spoon flour into the cup loosely and level off; do not scoop or pack it down.
How many cups is 250g of butter?
250g of butter is approximately 1 ⅛ cups, or 2 sticks plus 1 ½ tablespoons. The standard UK butter block is 250g, and the standard US stick is 113g (¼ pound), so a UK block is roughly 2 ¼ sticks. For recipes that call for 1 cup of butter, use 227g.
Are cups the same in the UK and US?
No. A US cup is 240ml. A UK cup (rare in modern recipes) was 284ml. Australia and Canada use 250ml. The vast majority of online recipes that use cups are American, so this converter assumes US cup conventions. For old British cookery books that use cup measures, the values will be roughly 18% under what the recipe expects.
Why does the converter give fractions?
Because measuring cups are marked in fractions. ¾ cup is a real measurement on a real cup; 0.75 cups is a number you have to translate. The fraction shown is the closest standard fraction (eighths, quarters, thirds, halves) to the actual decimal, which is shown underneath for reference.
