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 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.

Frequently Asked Questions
How do I convert Grams per second to Kilograms per second?
A metric mass-flow unit equal to exactly 10⁻³ kg/s. To convert Grams per second to Kilograms per second, multiply by 0.001. For example, 25 g/s equals 0.025 kg/s.
How many Kilograms per second are in 1 Gram per second?
There are 0.001 Kilograms per second in 1 Gram per second.
How many Grams per second are in 1 Kilogram per second?
There are 1000 Grams per second in 1 Kilogram per second.
What is the formula for Gram per second to Kilogram per second conversion?
The formula is: multiply by 0.001. This means 1 g/s = 0.001 kg/s.
Is a Gram per second bigger than a Kilogram per second?
Yes. One Gram per second is larger than one Kilogram per second because 1 g/s equals 0.001 kg/s, which is less than 1.
When do you need to convert between Grams per second and Kilograms per second?
The SI unit of mass flow rate (ISO 80000-4 §4-30) — mass of substance crossing a fixed boundary per unit time. Gram per second and Kilogram per second are both mass flow units, so conversion comes up whenever one source of information uses one unit and another uses the other — a classic cross-reference challenge in engineering, trade, travel, and everyday life.
