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 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 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.
