Convert Square centimetres per hour to Square feet per second
Convert Square centimetres per hour (cm²/h) to Square feet per second (ft²/s) instantly and accurately.
Conversion Formula
ft²/s = cm²/h × 2.989975116e-7
About Square centimetres per hour
The square centimetre per hour (cm²/h) equals 1/36 000 000 m²/s. Environmental geophysicists use cm²/h when measuring heat flow in sedimentary rock columns or permafrost layers. Granite has a diffusivity of ≈36 cm²/h; dry sand ≈9 cm²/h. 1 cm²/h = 1e-4/3600 m²/s ≈ 2.778 × 10⁻⁸ m²/s.
About Square feet per second
The square foot per second (ft²/s) equals 0.09290304 m²/s, the imperial base unit for thermal diffusivity analogous to m²/s. It is used in US aerospace engineering and combustion research for highly conductive materials and high-temperature plasmas. Diamond, the most thermally diffusive solid at ≈7 cm²/s, converts to ≈0.0075 ft²/s; silver to ≈0.00167 ft²/s. 1 ft²/s = 3600 ft²/h = 0.09290304 m²/s.
