How many kg is one cup?

Answer 1

Kilograms measures MASS not VOLUME. However, CUPS measures VOLUME, not MASS. Therefore it all depends on WHAT you're putting in that cup.

A better question would be, "What is the mass of one cup of ______?" And then fill in the blank. But since the MKS (meters-kilograms-seconds) system often is not used with the English Gravitational system (feet-pounds-seconds), a more reasonable question might be "what is the mass of <so many> ml of the substance ____ weigh?"

So a simple example might be "What is the mass of 150 ml of water?" (Answer 150 gm). Or other other hand how much does a cup of water weight (about a half pound).)

Answer 2

One cup is approximately 0.24 kg. The weight can vary slightly depending on the ingredient being measured.

Answer 3

it depends on what you're measuring...
