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 hundredweights per hour
The long hundredweight per hour (cwt/h, UK) equals 50.80234544/3600 ≈ 0.014112 kg/s. The long hundredweight (112 lb = 8 stone) was the standard commercial weight in British wholesale trade. It survives in historic UK cement and bulk-aggregate pricing sheets and in some British agricultural markets. 1 long cwt/h ≈ 0.014112 kg/s = 112 lb/h.
