About Kilogram per second (kg/s)
The SI unit of mass flow rate (ISO 80000-4 §4-30) — mass of substance crossing a fixed boundary per unit time. kg/s is the universal unit in chemical, mechanical, and propulsion engineering for process material balances, combustion-stoichiometry analysis (air and fuel flow rates), turbomachinery design (compressor and turbine corrected mass flow), and rocket propulsion. Coriolis mass-flow meters per ASME PTC 19.5 and Micro Motion CMF / Endress+Hauser Promass series industrial transmitters report directly in kg/s. Reference scale: Space Shuttle main engines consumed ~512 kg/s of LH2/LOX propellant each at full thrust (3 × ~1.5 GW power equivalent); the SpaceX Raptor 2 engine ~720 kg/s; a commercial high-bypass turbofan burns ~3 kg/s of Jet A at cruise; a 100 MW gas turbine ~300 kg/s air mass flow. Convert to lb/s by dividing by 0.4536; to kg/hr by multiplying by 3,600; to lb/hr by multiplying by 7,937.
About Kilogram per hour (kg/hr)
A metric mass-flow unit equal to exactly 1/3600 kg/s. kg/hr is the working unit for industrial process streams, boiler steam-output ratings (DIN EN 12952 water-tube boiler specs and EN 12953 shell-boiler specs are typically quoted in kg/hr or t/hr), petroleum refinery throughput, chemical-plant material balances (Aspen HYSYS, CHEMCAD, AVEVA SimCentral, gPROMS default unit for material-stream rates), bulk material handling, food and beverage manufacturing (production-line throughput per Codex Alimentarius), and HVAC make-up-water rates in commercial humidification systems. Reference values: a typical industrial steam boiler produces 5,000-50,000 kg/hr of saturated steam; a refinery atmospheric-crude distillation column processes 50,000-500,000 kg/hr of feed; a 100 MW gas-turbine combined-cycle gas-flow ~360,000 kg/hr air; a craft brewery's wort kettle 500-5,000 kg/hr; an espresso machine steam wand ~15 kg/hr of vapour. Convert kg/hr to lb/hr by multiplying by 2.2046; to t/hr by dividing by 1,000; to kg/s by dividing by 3,600.

Understanding Kilograms per second
The Kilogram per second (symbol: kg/s) is a unit of mass flow rate. The SI unit of mass flow rate (ISO 80000-4 §4-30) — mass of substance crossing a fixed boundary per unit time. kg/s is the universal unit in chemical, mechanical, and propulsion engineering for process material balances, combustion-stoichiometry analysis (air and fuel flow rates), turbomachinery design (compressor and turbine corrected mass flow), and rocket propulsion. Coriolis mass-flow meters per ASME PTC 19.5 and Micro Motion CMF / Endress+Hauser Promass series industrial transmitters report directly in kg/s.
