Convert Cubic kilometres per year to Cubic inches per minute
Convert Cubic kilometres per year (km³/yr) to Cubic inches per minute (in³/min) instantly and accurately.
Conversion Formula
in³/min = km³/yr × 116023545.7
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.
About Cubic inches per minute
The cubic inch per minute (in³/min) equals 1.6387064×10⁻⁵/60 ≈ 2.731×10⁻⁷ m³/s, common in US pneumatic and hydraulic circuit design. Air-tool consumption is rated in SCIM (standard cubic inches per minute); small hydraulic cylinders advancing at 10 in/min with 1 in² bore consume 10 in³/min: exactly 0.163 mL/s. 1 in³/min ≈ 2.731×10⁻⁷ m³/s.
