Conversion Formula
ft²/h = ft²/min × 60
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 feet per hour
The square foot per hour (ft²/h) equals 0.3048²/3600 ≈ 2.581 × 10⁻⁵ m²/s. It is the standard US unit for thermal diffusivity in the BTU-ft-h system, used alongside heat-transfer and mass-transfer calculations. Air at 20 °C ≈ 0.573 ft²/h; water at 20 °C ≈ 0.0096 ft²/h. 1 ft²/h ≈ 25.81 cSt.
