Grams to Cups Calculator
Convert grams to US cups (and cups back to grams) by ingredient. Flour is about 120 g per cup; granulated sugar about 200 g. A cup of water is not a cup of flour.
This grams to cups calculator turns a scale reading into US cups using typical densities — flour, sugar, brown sugar, butter, and more. From grams to cups: cups = grams ÷ grams per cup. How much is grams to cups depends on the food. Scooping flour packed vs spooned changes the weight; prefer grams when the recipe lists them.
Kitchen estimates from typical US-cup densities. Brands, packing, and humidity change flour especially. Prefer a scale when the recipe lists grams.
Grams to cups conversion formula
cups = grams ÷ (grams per US cup). grams = cups × grams per cup.
Flour: cups = g ÷ 120. Sugar: cups = g ÷ 200. 100 g flour ≈ 0.83 cup; 100 g sugar = 0.50 cup. Tablespoons = cups × 16.
How to use this grams to cups calculator
- Select the ingredient (start with flour or sugar).
- Choose Grams → cups or Cups → grams.
- Enter the amount (try 100 g or 240 g).
- Read US cups (and tablespoons). For flour, 120 g per cup is the density used here.
About this calculator
How do you convert grams to cups? Pick the ingredient, enter grams, divide by that ingredient’s grams per US cup. How many grams cup / how many grams per cup: all-purpose flour 120 g, granulated sugar 200 g, packed brown sugar 220 g, butter 227 g, water 237 g, milk 240 g. Sugar grams to cups: 200 g = 1 cup; 100 grams to cups of sugar is 0.50 cup. Flour: 120 g = 1 cup, so 240 g ≈ 2 cups (the default on this page).
Grams to cups conversion is not one factor for every food. Water’s 1 g ≈ 1 ml, but flour is lighter. This grams to cups converter uses a US cup (8 fl oz, 236.6 ml), not a metric 250 ml cup. UK recipes that say “cup” may assume 250 ml — the chart will be slightly off.
The calculator also runs cups → grams. Tablespoons = cups × 16. Ounces shown on the reverse path are avoirdupois (weight), not fluid ounces. Brands, humidity, and how you fill the cup shift flour more than sugar. When a bag or baker specifies grams, use a scale.
Examples
Flour: 240 g
240 ÷ 120 = 2.00 US cups (about 32 tablespoons).
Sugar: 100 g
100 ÷ 200 = 0.50 US cup.
Cups to grams: 1 cup butter
1 × 227 = 227 g (about 8.0 oz).
Grams to cups chart (US cup)
Typical kitchen densities used here. Your bag may differ; treat this grams to cups conversion table as a starting point, not a lab certificate.
- All-purpose flour: 120 g per cup (100 g ≈ 0.83 cup)
- Granulated sugar: 200 g per cup (100 g = ½ cup)
- Brown sugar, packed: 220 g per cup
- Butter: 227 g per cup
- Water: 237 g · milk: 240 g · oil: 218 g · honey: 340 g
- White rice (uncooked): 185 g · rolled oats: 90 g · cocoa: 85 g · salt: 273 g
Flour vs sugar, and weighing
Flour is about 60% of sugar’s weight per cup, so a grams to cups calculator for flour must not use the sugar factor. Packed brown sugar is denser than white sugar. Cocoa and oats are light; honey and salt are heavy.
If a European recipe uses grams only, stay on the scale. Use this converter when you only have cups, or when scaling with the recipe scaler after you have one unit.
