FPM to m/s Converter
1 foot per minute equals 0.00508 meters per second. Since 1 foot = 0.3048 m and 1 minute = 60 seconds, the conversion factor is 0.3048 ÷ 60 = 0.00508. FPM is the standard unit for...

Examples
100 fpm
= 0.508 m/s
100 FPM = 0.508 m/s
500 fpm
= 2.54 m/s
500 FPM = 2.54 m/s
Where is this used?
Fume hood face velocity specifications, cleanroom air velocity requirements, and ventilation system commissioning reports.
Frequently Asked Questions
What is typical duct velocity in m/s?
Residential ductwork: 2–4 m/s (400–800 FPM). Commercial duct mains: 5–10 m/s (1000–2000 FPM). High-velocity systems: 10–20 m/s (2000–4000 FPM).
How do I convert m/s back to FPM?
Divide m/s by 0.00508. For quick estimates, multiply m/s by 196.85 to get FPM.
What is the recommended fume hood face velocity?
Typical fume hood face velocity is 100 FPM (0.508 m/s) per ANSI/ASHRAE 110 standards. Low-flow hoods operate at 60–80 FPM.
