Why are liquids like water measured in ounces, liters, gallons, etc oppose to weight like lbs, kilos, grams, etc. ?
In: Chemistry
It’s very easy to measure flow rate throw a pipe to find out how much volume flowed through it. Determining the mass would be much harder.
Compare that to solids, it’s very easy to weigh them, but hard to determine their volume because they don’t fill a space without gaps.
And since liquids have constant density (at assumed constant temperature), volume and mass are linked anyway
