What is a cubic metre?
Exactly a thousand litres, by the definition of the litre. The SI unit of volume, and how the rest of the world orders concrete.
What is a cubic inch?
Exactly 16.387064 millilitres, since the inch is exactly 25.4 mm. American engine displacement was quoted in it until the 1980s — a 350 small block is 5.7 litres.
How many cubic inches are in a cubic metre?
One cubic metre is 61023.744 cubic inches. Going the other way, one cubic inch is 1.6387 × 10^-5 cubic metres. Both figures come from the same defined relation rather than from a measurement, which is why they are the same today as they were in 1959.
