Convert Square feet per hour to Square centimetres per hour
Convert Square feet per hour (ft²/h) to Square centimetres per hour (cm²/h) instantly and accurately.
Conversion Formula
cm²/h = ft²/h × 929.0304
About Square feet per hour
The square foot per hour (ft²/h) equals ≈2.581 × 10⁻⁵ m²/s and is the dominant unit in US engineering practice for thermal diffusivity of building materials and industrial insulation. ASHRAE handbooks, Perry's Chemical Engineers' Handbook, and NFPA fire-resistance tables all list diffusivity in ft²/h. Steel: ≈0.4-0.5 ft²/h; concrete: ≈0.023 ft²/h; mineral wool: ≈0.005 ft²/h. 1 ft²/h = 0.09290304/3600 m²/s.
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.
