Conversion Formula
cm²/min = ft²/h × 15.48384
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 minute
The square centimetre per minute (cm²/min) equals ≈1.667 × 10⁻⁶ m²/s, a transitional unit seen in older French and Soviet thermal engineering literature. Some food-science papers on heat penetration into frozen products express diffusivity in cm²/min to keep values close to unity. 1 cm²/min = 1e-4/60 m²/s ≈ 1.667 × 10⁻⁶ m²/s.
