About Pounds per second

The pound per second (lb/s) equals 0.45359237 kg/s, widely used in aerospace and large industrial equipment. A Saturn V first-stage engine consumed ≈13 short tons of propellant per second, equal to ≈26 000 lb/s; a typical large centrifugal pump handling water moves ≈500-2000 lb/s at operating flow. 1 lb/s = 0.45359237 kg/s ≈ 3 600 lb/h.

About Slugs per second

The slug per second (slug/s) equals 14.5939029372 kg/s, derived from the Imperial system where 1 slug = 1 lb·s²/ft ≈ 14.594 kg. The slug is the coherent mass unit in the foot-pound-second system; rocket propulsion engineers using US customary units express mass flow in slug/s. A standard American rocket engine consuming 75 000 lb/s of propellant corresponds to ≈75 000/32.174 ≈ 1 830 slug/s. 1 slug/s = 14.5939029372... kg/s.
