About Pound per minute (lb/min)
An imperial mass-flow unit equal to exactly 1/60 of lb/s ≈ 7.5599 × 10⁻³ kg/s. lb/min is used for medium-timescale US engineering applications where the per-second timebase would give awkwardly small decimals and the per-hour timebase too-large numbers. Common uses: HVAC humidification (commercial steam-injection humidifiers rated 5-100 lb/min per ASHRAE Handbook), compressed-air-system purge and surge calculations, pneumatic-conveying mass-handling rates per CEMA standards (food-processing line dispensing of flour, sugar, salt, dried fruit; pharmaceutical excipient transfer per ISPE Baseline Guide for solid-dosage manufacturing), powder-coating gun flow rates (typical 1-5 lb/min), legacy reciprocating internal-combustion-engine air-flow specifications (lb/min was the standard automotive MAF unit before the industry transitioned to g/s in the early 2000s on OBD-II Mode 01 PID 0x10 per SAE J1979), and packaging-line throughput specifications for bulk consumer products. Convert lb/min to kg/s by multiplying by 7.5599 × 10⁻³; to g/s by multiplying by 7.5599; to lb/hr by multiplying by 60; to lb/s by dividing by 60.
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.

Understanding Pounds per minute
The Pound per minute (symbol: lb/min) is a unit of mass flow rate. An imperial mass-flow unit equal to exactly 1/60 of lb/s ≈ 7.5599 × 10⁻³ kg/s. lb/min is used for medium-timescale US engineering applications where the per-second timebase would give awkwardly small decimals and the per-hour timebase too-large numbers. Common uses: HVAC humidification (commercial steam-injection humidifiers rated 5-100 lb/min per ASHRAE Handbook), compressed-air-system purge and surge calculations, pneumatic-conveying mass-handling rates per CEMA standards (food-processing line dispensing of flour, sugar, salt, dried fruit; pharmaceutical excipient transfer per ISPE Baseline Guide for solid-dosage manufacturing), powder-coating gun flow rates (typical 1-5 lb/min), legacy reciprocating internal-combustion-engine air-flow specifications (lb/min was the standard automotive MAF unit before the industry transitioned to g/s in the early 2000s on OBD-II Mode 01 PID 0x10 per SAE J1979), and packaging-line throughput specifications for bulk consumer products. Convert lb/min to kg/s by multiplying by 7.5599 × 10⁻³; to g/s by multiplying by 7.5599; to lb/hr by multiplying by 60; to lb/s by dividing by 60.
It belongs to the imperial measurement system.
Pounds per minute are commonly used in chemical processing, fuel systems, and environmental monitoring.
Understanding Kilograms per second
The Kilogram per second (symbol: kg/s) is a unit of mass flow rate.
