m³ stands for Cubic meter, a metric and SI unit abbreviation.

SI unit of volume, a cube 1 m on each side, holding 1,000 liters or about 264 US gallons. Utility bills in many countries measure water and gas in m³, and engineers use it for concrete, earthworks and river flow in m³/s.

Example: Our water bill shows 14 m³ used this month, up from 11 last month.

Usage notes

Also written cu m, m3 or, in freight, CBM. A cubic meter of fresh water has a mass of about one tonne. European gas bills convert the m³ reading into kilowatt-hours using a calorific value. Engineers distinguish "normal" or "standard" cubic meters, measured at fixed temperature and pressure, for gases.
