About Long hundredweights per day
The long hundredweight per day (cwt/d, UK) equals 50.80234544/86400 ≈ 5.880×10⁻⁴ kg/s, encountered in legacy British industrial reports for colliery output, port-handling capacity, and sugar-refinery throughput. Historical British coal-mine productivity was routinely expressed in long cwt per miner per day. 1 long cwt/d ≈ 5.880×10⁻⁴ kg/s = 112 lb/d.
About Grains per hour
The grain per hour (gr/h) equals 6.479891×10⁻⁵/3600 ≈ 1.800×10⁻⁸ kg/s, used in HVAC psychrometric calculations for dehumidifier capacity and moisture-removal rates. ASHRAE load calculation spreadsheets report latent loads in grains of water per hour; a typical residential dehumidifier removes 5×10⁵-2×10⁶ gr/h. 1 gr/h ≈ 1.800×10⁻⁸ kg/s.
