About Short tons per second
The short ton per second (ton/s, US) equals 907.18474 kg/s, used for the very highest industrial and military throughput rates. The Space Shuttle Main Engine consumed propellant at ≈480 kg/s LOX + 160 kg/s LH2 ≈ 640 kg/s ≈ 0.71 ton/s; a large blast-furnace tap discharges molten iron at 1-3 ton/s. 1 short ton/s = 907.18474 kg/s = 2 000 lb/s.
About Pounds per day
The pound per day (lb/d) equals 0.45359237/86400 ≈ 5.249×10⁻⁶ kg/s, used in wastewater engineering for reporting biochemical oxygen demand (BOD) loads, nutrient loadings, and sludge production. US NPDES permits set effluent mass-load limits in lb/d; a municipal WWTP serving 10 000 people generates roughly 1 500-3 000 lb/d of dry sludge solids. 1 lb/d ≈ 5.249×10⁻⁶ kg/s.
