Just today I’ve noticed in the wrap of my liquid soap there’s a “290g/300ml” on it. Weren’t those two measures supposed to be equivalent? Or have they lied to me my whole life? Lol
In: Chemistry
Kilograms and Liters are *not* equivalent. Kilograms are a measurement of mass, Liters a measurement of volume. Some liquids can be lighter or heavier while still occupying the same physical space. This is called density.
A liter of water does have the mass of 1 kilogram. However anything that is not as dense as water will weight different things at 1 liter. Soap is not water (it has other stuff in it) so it doesn’t have to be 1kg at 1l.
