About US pints per minute
The US pint per minute (pt/min) equals 3.785411784×10⁻³/8/60 ≈ 7.886×10⁻⁶ m³/s, a unit encountered in US home-brewing, small-batch winery transfers, and consumer-grade pump ratings. A standard kitchen faucet running at 2 US gal/min produces 16 pt/min; a small submersible pond pump rated 50 gal/h delivers ≈27 pt/min. 1 US pt/min ≈ 7.886×10⁻⁶ m³/s.
About UK gallons per minute
The UK (imperial) gallon per minute (gpm) equals 4.54609×10⁻³/60 ≈ 7.577×10⁻⁵ m³/s, historically used in British plumbing design, pump curves, and water-treatment plant sizing. Pre-metric UK water-industry capacity tables and pump manufacturers quoted flows in UK gal/min; legacy British Standard BS EN pump curves often show both units. 1 UK gpm ≈ 7.577×10⁻⁵ m³/s ≈ 4.546 L/min.
