Convert Square centimetres per second to Square feet per hour
Convert Square centimetres per second (cm²/s) to Square feet per hour (ft²/h) instantly and accurately.
Conversion Formula
ft²/h = cm²/s × 3.87500775
About Square centimetres per second
The square centimetre per second (cm²/s) equals 10⁻⁴ m²/s, numerically identical to 1 stoke (St). It is the explicit CGS dimensional form, preferred in dimensional analysis or when avoiding named units. 1 cm²/s = 1 St = 100 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.
