Convert Square metres per minute to Square feet per hour
Convert Square metres per minute (m²/min) to Square feet per hour (ft²/h) instantly and accurately.
Conversion Formula
ft²/h = m²/min × 645.834625
About Square metres per minute
The square metre per minute (m²/min) equals 1/60 m²/s ≈0.01667 m²/s, a non-standard unit seen in some process-engineering contexts where heat soak times are measured in minutes rather than seconds. Nuclear fuel rod thermal analysis and large refractory furnace lining design occasionally cite diffusivity in m²/min. 1 m²/min = 1/60 m²/s ≈ 6000 cm²/s.
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.
