About Gram per second (g/s)
A metric mass-flow unit equal to exactly 10⁻³ kg/s. g/s is the working unit for small-scale and instrumentation-grade mass-flow measurement applications: automotive Mass Air Flow (MAF) sensor output (typical idle 2-4 g/s, cruise 10-30 g/s, wide-open-throttle on a 3.5 L V6 ~100-180 g/s), engine-management data-logging (HP Tuners, EFILive, Cobb AccessPort, OpenECU all report MAF in g/s for North American vehicles), automotive dyno-tuning and powertrain calibration software, OBD-II Mode 01 PID 0x10 (MAF rate) which is defined as g/s per SAE J1979 and ISO 15031-5, laboratory fuel-injector flow-bench measurement using SAE J1832 procedures, medical respiratory-gas delivery (HFNC high-flow nasal cannula 60-120 g/s of warmed/humidified air-O₂ mix per AARC Clinical Practice Guidelines), small-scale chemical-process dosing (Bronkhorst / Sensirion / Honeywell mass-flow controllers commonly used in semiconductor fabs and pharmaceutical manufacturing), and analytical-instrument carrier-gas flows. Convert g/s to kg/s by dividing by 1,000; to lb/min by multiplying by 0.1323; to kg/hr by multiplying by 3.6.
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 Grams per second
The Gram per second (symbol: g/s) is a unit of mass flow rate. A metric mass-flow unit equal to exactly 10⁻³ kg/s. g/s is the working unit for small-scale and instrumentation-grade mass-flow measurement applications: automotive Mass Air Flow (MAF) sensor output (typical idle 2-4 g/s, cruise 10-30 g/s, wide-open-throttle on a 3.5 L V6 ~100-180 g/s), engine-management data-logging (HP Tuners, EFILive, Cobb AccessPort, OpenECU all report MAF in g/s for North American vehicles), automotive dyno-tuning and powertrain calibration software, OBD-II Mode 01 PID 0x10 (MAF rate) which is defined as g/s per SAE J1979 and ISO 15031-5, laboratory fuel-injector flow-bench measurement using SAE J1832 procedures, medical respiratory-gas delivery (HFNC high-flow nasal cannula 60-120 g/s of warmed/humidified air-O₂ mix per AARC Clinical Practice Guidelines), small-scale chemical-process dosing (Bronkhorst / Sensirion / Honeywell mass-flow controllers commonly used in semiconductor fabs and pharmaceutical manufacturing), and analytical-instrument carrier-gas flows.
