Half a cup in grams depends on what you’re measuring, because each ingredient has a different density.

Quick Scoop

For common kitchen ingredients, half a cup is approximately:

  • Water or other thin liquids: about 120 g
  • Granulated sugar: about 100 g
  • Brown sugar (packed): about 110–120 g
  • All-purpose flour (scooped and leveled): about 60 g
  • Butter (solid): about 113 g (1 US stick)

Why there’s no single answer

  • A cup measures volume, while grams measure weight, so they only match neatly for water-like liquids.
  • Half a cup of something light and airy (like flour) will weigh much less than half a cup of something dense (like honey or nuts).

Simple rule of thumb

  • If a recipe does not specify the ingredient and just says “half a cup in grams,” the safest assumption is that you must look it up for that exact ingredient or use a kitchen scale for accuracy.

TL;DR: There isn’t one universal number for “how much is half a cup in grams” because it changes with each ingredient, but for many liquids it’s around 120 g, and for common baking ingredients like flour or sugar it often falls between 60 g and 115 g for half a cup.
