How to convert us cup to gram
This conversion crosses volume and weight, so it depends on the ingredient. We use a US cup = 236.5882 mL and all-purpose flour ≈ 125 g per US cup.
Formula:
grams = cups × 236.5882 × density, where density = 125 ÷ 236.5882 g/mL
Worked example: 1 us cup = 125 gram (Spoon-and-level; scooped can be 140–160 g).
