Cat litter in litres? - 10/17/12 06:19 PM
I buy the stuff every week and get 10 litres of it but only today did I stop and wonder why litres? I thought only liquids were measured in litres? But according to Wikipedia:
Notice this "One litre of water has a mass of almost exactly one kilogram when measured at its maximal density, which occurs at about 4 °C."? Why not just measure in Kgs then?
Still seems odd to me

Litres are most commonly used for items (such as fluids and solids that can be poured) which are measured by the capacity or size of their container, whereas cubic metres (and derived units) are most commonly used for items measured either by their dimensions or their displacements. The litre is often also used in some calculated measurements, such as density (kg/L), allowing an easy comparison with the density of water.
One litre of water has a mass of almost exactly one kilogram when measured at its maximal density, which occurs at about 4 °C. Similarly: 1 millilitre of water has a mass of about 1 g; 1000 litres of water has a mass of about 1000 kg . This relationship holds because the gram was originally defined as the mass of 1 mL of water; however, this definition was abandoned in 1799 because the density of water changes with temperature and, very slightly, with pressure.
