Convert Cubic metres per minute to Cubic kilometres per year
Convert Cubic metres per minute (m³/min) to Cubic kilometres per year (km³/yr) instantly and accurately.
Conversion Formula
km³/yr = m³/min × 0.00052596
About Cubic metres per minute
The cubic metre per minute (m³/min) equals 1/60 m³/s ≈ 1.667×10⁻² m³/s, used in large compressor and blower specifications, tunnel ventilation design, and industrial air-handling. A mine-ventilation fan may move 1 000-5 000 m³/min; an industrial rotary-screw compressor delivers 5-50 m³/min of free air. 1 m³/min = 1 000 L/min ≈ 35.31 ft³/min ≈ 264.2 US gal/min.
About Cubic kilometres per year
The cubic kilometre per year (km³/yr) equals 10⁹/(365.25×86400) ≈ 31.688 m³/s, the unit used in global hydrology, glaciology, and climate science for river basin runoff, ice-sheet mass balance, and groundwater storage change. Total global freshwater river runoff is ≈37 000 km³/yr; the Amazon alone contributes ≈6 600 km³/yr; the Greenland ice sheet loses ≈280 km³/yr to melt and calving. 1 km³/yr ≈ 31.69 m³/s.
