Half Cup in Grams: ½ Cup Conversion for Every Common Ingredient

Reference table  ·  Updated August 2026

Quick Answer

½ US cup of all-purpose flour = 63 g. ½ cup of granulated sugar = 100 g. ½ cup of butter = 114 g. ½ cup of whole milk = 122 g. ½ cup of honey = 170 g.

What is ½ cup?

Half a cup is one of the most-used measurements in baking. Because a cup measures volume, ½ cup of flour weighs roughly 63 g while ½ cup of honey weighs 170 g. This page gives the gram weight for one half-cup of every common ingredient using the US cup (118.3 ml) and the metric cup (125 ml).

A half cup is exactly one half of the cup unit. In the US customary system that is 118.294 ml. In the metric system it is 125 ml. Half a cup equals 8 US tablespoons or 24 US teaspoons. Because the cup measures volume, the gram weight at this volume is determined entirely by the density of the ingredient.

US cup vs metric cup at this volume

US cup (½ cup): 118.3 ml  ·  Metric cup (½ cup): 125 ml  ·  ½ cup = 8 US tablespoons = 24 US teaspoons

Why gram weights differ by ingredient

A cup measures volume. Different ingredients have different densities, so the same volume holds different masses. This is why ½ cup of honey weighs far more than ½ cup of flour.
