per thousand liters

Cost per volumeexact by definition

Cost per thousand litres is numerically identical to cost per cubic metre, since a cubic metre is exactly one thousand litres. It exists as a separate entry because water and chemical tariffs are sometimes written per thousand litres and the equality is not always obvious to the reader. The conversion factor of one is exact by definition of the litre.
