How to Convert Pounds per second to Pounds per minute

Formula

To convert Pounds per second (lb/s) to Pounds per minute (lb/min): multiply by 60

Step-by-Step

  1. Start with your value in Pounds per second (lb/s).
  2. Multiply by 60 to perform the conversion.
  3. The result is your value expressed in Pounds per minute (lb/min).

Conversion Factor

1 lb/s = 60 lb/min

Reverse Factor

1 lb/min = 0.0166667 lb/s

Worked Example

Convert 25 Pounds per second to Pounds per minute: 25 lb/s = 1500 lb/min

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.

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.

Understanding Pounds per second

The Pound per second (symbol: lb/s) is a unit of mass flow rate. 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.

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.

It belongs to the imperial measurement system.

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

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.

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.
