How to measure brewed coffee

Brewed black coffee is almost entirely water, so it weighs essentially the same per cup.

Because a cup measures volume rather than weight, the most reliable way to measure brewed coffee is with a digital kitchen scale. If you are working from cups, keep your technique consistent every time so your results are repeatable. For more, see our guide on baking by weight versus volume.

Brewed coffee conversions: FAQ

Why doesn't a cup of brewed coffee weigh the same as a cup of water?

A cup measures volume, not weight. Brewed coffee is less dense than water (237 g versus 237 g per cup), so the same volume has a different weight. Weighing in grams is the most accurate way to measure it.
