Convert flour grams or ounces to US or metric cups and back, adjusted by flour type and measuring method for practical baking estimates.
Assumptions Assumptions
- Conversions are weight-to-volume for flour using typical kitchen densities; results are estimates.
- Base grams per US cup (spoon & level): AP = 120 g; Bread = 120 g; Cake = 113 g; Pastry = 113 g; Whole wheat = 120 g.
- Measuring method multipliers: spoon & level = 1.00; scooped/dipped = 1.10; sifted = 0.90.
- Unit standards: US cup = 236.588 mL; Metric cup = 250 mL; 1 oz = 28.349523125 g.
- Humidity, brand, and technique can change actual packing and therefore grams per cup.
When to Use This Calculator
- Converting recipes written in grams/ounces to cups when a scale isn’t available.
- Standardizing recipe cards across US and metric cup sizes.
- Estimating substitutions when switching flour types or measuring methods.
Input Definitions
- Flour Type — sets the baseline grams per US cup.
- Measuring Method — adjusts density: scooped packs more; sifted packs less.
- Flour Weight — enter in grams or ounces.
- Cups — choose US cup (236.588 mL) or Metric cup (250 mL).
- Conversions — cups = grams ÷ (g per cup); grams = cups × (g per cup).
Flour Grams to Cups Formula
The following formulas convert flour between weight and volume; the grams-per-cup value depends on the flour type, measuring method, and chosen cup size.
\mathrm{cups} = \frac{\mathrm{grams}}{\mathrm{g\ per\ cup}}\\
\mathrm{grams} = \mathrm{cups}\times \mathrm{g\ per\ cup}- US cup = 236.588 mL
- Metric cup = 250 mL
- Base grams per US cup (spoon & level): AP = 120 g; Bread = 120 g; Cake = 113 g; Pastry = 113 g; Whole wheat = 120 g
- Method multipliers: Scooped × 1.10; Sifted × 0.90
- 1 oz = 28.349523125 g

How do you convert grams to cups of flour? Divide grams by the grams-per-cup for your flour and measuring method (e.g., AP spoon & level ≈ 120 g per US cup: cups = grams ÷ 120).
How do you convert cups to grams of flour? Multiply cups by the grams-per-cup for your flour and measuring method (e.g., grams = cups × 120 g for AP spoon & level, US cup).
Example Problem
Convert 300 g of all-purpose flour (spoon & level) to US cups.
Use the formula: cups = grams ÷ (g per cup).
cups = 300 ÷ 120 = 2.5 cups
