Why is it that 1 litre of water weighs 1 kg while this doesn't apply for other liquids?
Interesting. So, are there any other common substances besides water that have their own weight/volume standards?
Not that I'm aware of off the top of my head, but there are certainly other materials with specific measurements used in various industries. For example, concrete is often measured by its volume in cubic meters, and certain chemicals might be measured in grams or milliliters.
