Conversion Formula
pt/s = km³/yr × 66968.85755
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 US pints per second
The US pint per second (pt/s) equals 3.785411784×10⁻³/8 ≈ 4.732×10⁻⁴ m³/s, used in US food-filling equipment rated in pints-per-second throughput. High-speed dairy-packaging lines filling 16 oz (1 pt) cartons can achieve 10-20 pt/s per lane. 1 US pt/s ≈ 4.732×10⁻⁴ m³/s = 0.4732 L/s = 7.5 US gal/min.
