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 Litres per day
The litre per day (L/d) equals 10⁻³/86400 ≈ 1.157×10⁻⁸ m³/s, standard in water-resource management, reverse-osmosis membrane rating, and daily per-capita water-use statistics. A residential reverse-osmosis unit produces 100-300 L/d of purified water; the WHO minimum for basic household use is 50 L/d per person. 1 L/d ≈ 1.157×10⁻⁸ m³/s.
