Baking Conversion Calculator — Cups to Grams
This baking conversion calculator converts cups to grams (and grams to cups) for common baking ingredients using accurate density values. 1 cup of flour = 120 g, 1 cup of sugar = 200 g, 1 cup of butter = 227 g. Select your ingredient and enter an amount to convert instantly.
Frequently Asked Questions
How many grams is 1 cup of flour?
1 cup of all-purpose flour weighs approximately 120 grams using the spoon-and-level method. If you scoop flour directly from the bag it can weigh 140–160 g due to compression. For consistent baking results, always use a kitchen scale.
How many grams is 1 cup of sugar?
1 cup of granulated white sugar weighs 200 grams. Brown sugar, packed, is similar at about 200–220 g. Powdered (confectioner's) sugar is lighter at about 120 g per cup.
How many grams is 1 cup of butter?
1 cup of butter weighs 227 grams (approximately 2 standard US sticks, or 8 oz). This is consistent because butter is a dense, uniform solid at room temperature.
Why do cups and grams differ for different ingredients?
A cup is a measure of volume (240 ml), while grams measure mass (weight). Different ingredients have different densities — honey is denser than flour, so 1 cup of honey is much heavier. This is why weight measurements in grams are more reliable for baking.
How do I convert 2 cups of flour to grams?
2 cups of flour × 120 g/cup = 240 grams. Use this calculator to convert any amount: select flour as the ingredient, choose Cups → Grams, and enter 2.
How many cups is 250g of sugar?
250 grams of sugar ÷ 200 g/cup = 1.25 cups. Select sugar as the ingredient, choose Grams → Cups, and enter 250 to confirm.
What is the difference between a US cup and a metric cup?
A US cup is 236.6 ml (often rounded to 240 ml), while an Australian/metric cup is 250 ml. A UK imperial cup is 284 ml. The density table in this calculator uses the US cup (240 ml). For metric cup conversions, multiply gram values by 250/240 ≈ 1.042.
How do I measure sticky ingredients like honey in cups?
For sticky ingredients like honey, lightly coat the measuring cup with cooking spray before filling. This helps the honey slide out cleanly. Alternatively, measure by weight in grams — 1 cup of honey = 340 g — which is far easier and more accurate.
Why Convert Cups to Grams?
Volume measurements like "cups" are imprecise for baking because the same cup can hold different weights of different ingredients. A cup of flour weighs only 120 g while a cup of honey weighs 340 g. Professional bakers and most European recipes use weight in grams for consistent, reproducible results.
Ingredient Density Table
| Ingredient | g per 1 cup | 1 cup in oz |
|---|---|---|
| All-Purpose Flour | 120 g | 4.2 oz |
| Sugar (granulated) | 200 g | 7.1 oz |
| Butter | 227 g | 8 oz |
| Milk | 244 g | 8.6 oz |
| Honey | 340 g | 12 oz |
| Cocoa Powder | 86 g | 3 oz |
| Rolled Oats | 90 g | 3.2 oz |
Values based on the US standard cup (236.6 ml) using the spoon-and-level method for flour. Scooped flour can weigh 20–30% more than spooned flour.
How to Measure Flour Correctly
Flour is the most common source of measurement errors in baking. The density table assumes the "spoon and level" method:
- Fluff the flour in its container with a spoon
- Spoon flour into the measuring cup without packing
- Level off the top with a straight edge
Scooping directly from the bag compresses flour and can give 150–160 g per cup instead of 120 g. For best results, use a kitchen scale.
