How to convert us cups to kilograms

1 cup = 0.125 kg, so multiply by 0.125 to go from US cups to kilograms of all-purpose flour. Going the other way, 1 kg = 8 cup.

kg = cup × 0.125
cup = kg × 8

Cups and spoons convert to weight using the weight per cup for all-purpose flour shown in the result; how the ingredient is measured (spooned, packed, sifted) changes it.

Worked example:

5 cup = 1182.9411825 mL
× 0.528344 g/mL (USDA FDC 168894, 1 cup = 125 g) = 625 g
= 0.625 kg
