Cups to Grams Calculator
Calculator
Cup-to-gram conversion depends on the ingredient's density — a cup of flour weighs much less than a cup of honey. Select your ingredient below to get the accurate gram equivalent. All values are based on standard US cups (236.588 mL) and widely accepted culinary density references.
Formula
Formula
grams = cups × (grams per cup for ingredient)
Each ingredient has a characteristic density. The calculator multiplies the number of cups by the standard gram-per-cup value for the selected ingredient. All values use the US cup (236.588 mL). Results may vary slightly depending on how the ingredient is measured (scooped vs spooned and levelled).
Worked example
A cookie recipe calls for 2 cups of all-purpose flour (unsifted). How many grams is that?
- 1.All-purpose flour (unsifted): 1 cup ≈ 125 g
- 2.2 cups × 125 g/cup = 250 g
- 3.In ounces: 250 g ÷ 28.3495 ≈ 8.82 oz
2 cups of all-purpose flour ≈ 250 g (8.82 oz).
Assumptions and limitations
- Uses US cup = 236.588 mL.
- Flour values assume the spoon-and-level method, not scooping directly with the cup (which compresses flour and adds ~20%).
- Brown sugar is assumed packed.
- Ingredient densities may vary by brand, moisture content, and measuring technique.
