Convert cubic meter to cubic millimeter

A cubic metre is 1,000 litres, also called a kilolitre on Australian water bills. Water meters count in it: one person uses roughly 45–55 m³ a year. Gas meters count cubic metres too, and the bill converts them to kilowatt-hours at about 10–11 kWh per m³. Removals and freight think in cubic metres as well, a 20-foot container holding 33 m³ and a concrete mixer truck 8 m³. The hectolitre, 100 l, is the unit of brewers and winemakers: breweries report output in hl and vineyards their yields in hl per hectare.
