How 8 grams of all-purpose flour was converted to cups
A cup is a volume, so its weight depends on the ingredient. One US cup of all-purpose flour weighs 125 grams (one hundred twenty-five), so divide 8 by 125.
8 g ÷ 125 g
=0.064 cups
(zero point zero six four cups)
The weight of the cup comes from USDA FoodData Central, SR Legacy entry 168894 “Wheat flour, white, all-purpose, enriched, bleached”, portion “1 cup” = 125 grams. Scooped ingredients vary with how they are filled — spooned in lightly, a cup weighs less; packed down, more — so for baking a kitchen scale is the exact tool and this figure the standard reference.
The other way round: how many grams in a cup
This page starts from grams and answers in cups. The opposite question — how many grams a recipe’s cups weigh, fractions like 1/2 and 2 1/2 included — is what the cups to grams converter is for. Both read the same USDA weights, so their numbers agree: one US cup of all-purpose flour is 125 grams there and here.
