Convert Square inches per minute to Square feet per hour
Convert Square inches per minute (in²/min) to Square feet per hour (ft²/h) instantly and accurately.
Conversion Formula
ft²/h = in²/min × 0.4166666667
About Square inches per minute
The square inch per minute (in²/min) equals 0.0254²/60 ≈ 1.075 × 10⁻⁵ m²/s. It appears in US coating and printing industry references where area coverage rates in in²/min are combined with kinematic flow data. 1 in²/min ≈ 10.75 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.
