About Grains per minute
The grain per minute (gr/min) equals 6.479891×10⁻⁵/60 ≈ 1.080×10⁻⁶ kg/s. This unit appears in HVAC humidity engineering: moisture added or removed from conditioned air is traditionally expressed in grains of water per pound of dry air per minute in US practice. A whole-house humidifier may evaporate 300-600 gr/min at design load. 1 gr/min ≈ 1.080×10⁻⁶ kg/s.
About Long tons per day
The long ton per day (long ton/d) equals 1 016.0469088/86400 ≈ 0.011760 kg/s, used in legacy British mining reports for daily colliery output and in Naval fuel-consumption logs. Historic British Admiralty fuel expenditure tables for Royal Navy warships used long ton/d for bunker coal or oil consumption at various speeds. 1 long ton/d ≈ 0.011760 kg/s ≈ 1.016 t/d.
