18 Grams to Cups
What 18 g looks like for every common baking ingredient
18 grams is about 6⅞ teaspoons of all-purpose flour, 4⅓ teaspoons of granulated sugar, or 3¾ teaspoons of butter — ⅛ of a US cup of flour. At this size spoons are easier to read than cup fractions.
There is no single answer to how many cups 18 grams is — it depends entirely on what you are measuring, because grams weigh and cups fill.
It also depends on whose cup you mean. A US cup is 236.6 ml; the metric cup used in the UK, Australia, New Zealand and Canada is 250 ml, so it holds about 5.7% more. Both columns are given below.
At this size spoons are easier to read than cup fractions: 18 g of flour is about 6⅞ teaspoons, and the table below gives both.
