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 Pound per second (lb/s)

An imperial mass-flow unit (≈ 0.453592 kg/s per NIST SP 811). lb/s is the dominant working unit in US aerospace engineering for turbomachinery: turbojet, turbofan, and turboprop engine performance data published by P&W, GE Aviation, Honeywell, and Rolls-Royce North America quote corrected and uncorrected mass flow in lb/s on type-certificate data sheets and FAR Part 33 power-plant certification documents per FAA Advisory Circular 33-2B. US-edition combustion textbooks (Glassman, Turns, Cengel & Boles) and gas-turbine engineering textbooks (Mattingly, Saravanamuttoo, Boyce) use lb/s throughout. Reference values: a GE F404 turbojet (F/A-18 Hornet) airflow ~146 lb/s at takeoff; GE9X (Boeing 777X) ~1,600 lb/s; CF6-80C2 (747-400) ~1,769 lb/s; F-1 first-stage rocket engine (Saturn V) ~5,683 lb/s of RP-1 + LOX; SpaceX Merlin 1D ~520 lb/s. Convert lb/s to kg/s by multiplying by 0.4536; to lb/hr by multiplying by 3,600; to lb/min by multiplying by 60.

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. 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.

It belongs to the metric measurement system.

Grams per second are commonly used in chemical processing, fuel systems, and environmental monitoring.
