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 minute
The long ton per minute (long ton/min) equals 1 016.0469088/60 ≈ 16.934 kg/s, historically used in British blast-furnace output measurements, port handling-rate calculations, and Royal Navy fuel-consumption specifications. A large grain terminal loading a Panamax vessel may achieve 4 000 long ton/h = ≈67 long ton/min. 1 long ton/min ≈ 16.934 kg/s.
