About Kilogram per second (kg/s)

The SI unit of mass flow rate — mass of substance crossing a boundary per unit time. Kg/s is the universal unit in chemical and mechanical engineering for process calculations, combustion analysis (air and fuel flow rates), turbine mass flow, and rocket propulsion. The Space Shuttle main engines consumed ~512 kg/s of propellant each during ascent; a commercial jet engine burns ~3 kg/s of fuel at cruise.

About Pound per second (lb/s)

An imperial mass-flow unit used in US aerospace engineering, combustion analysis, and some heavy-industry process engineering. Turbojet engine specification sheets and US-edition combustion textbooks commonly use lb/s for air and fuel flow. 1 lb/s ≈ 0.454 kg/s.
