Convert Square feet per minute to Square inches per second
Convert Square feet per minute (ft²/min) to Square inches per second (in²/s) instantly and accurately.
Conversion Formula
in²/s = ft²/min × 2.4
About Square feet per minute
The square foot per minute (ft²/min) equals 0.3048²/60 ≈ 1.548 × 10⁻³ m²/s. It appears in US HVAC, ventilation, and turbine-cooling design where velocities are quoted in ft/min. 1 ft²/min ≈ 1548 cSt.
About Square inches per second
The square inch per second (in²/s) equals 0.0254² = 6.4516 × 10⁻⁴ m²/s. It is the coherent FPS kinematic unit based on the inch, found in US fluid power, hydraulics, and bearing-design references. 1 in²/s = 645.16 cSt = 6.4516 St.
