Calibrated Measurement Condition: Spooned and leveled
Exact Formula

Calculation & Mathematical Derivation

To convert 100 grams of Cornstarch (Corn Flour UK) into US Customary measuring cups (236.6 mL):

Cups = Weight in Grams ÷ Grams per Cup (Bulk Density)
Cups = 100g ÷ 128g/cup = 0.78 cups (kitchen fraction: 3/4 cups)
Tablespoons = 100g ÷ 8.00g/tbsp = 12.5 tablespoons

This calculation is calibrated specifically for Spooned and leveled under standard kitchen conditions (sourced from USDA FoodData Central (FDC ID 169697)).

Technique Note: Gelatinizes at 144°F to 162°F (62°C–72°C); boiling too vigorously can shear starch molecules and thin the sauce.
