How many cups is 18 grams?

Answer

There is no single number — it depends on the ingredient. 18 grams fills

from 0.0531 cups (honey) to 0.22 cups (rolled oats)

The table gives all 19 of them, with the packed, sifted and cooked states on rows of their own, each from the weight of one US cup (236.6 ml) in USDA FoodData Central; water is counted from its volume.

How 18 grams of all-purpose flour was converted to cups

cups = grams ÷ grams in one US cup

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 18 by 125.

18 g ÷ 125 g

≈

0.14 cups

(zero point one 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.
