Convert Square feet per minute to Square feet per hour
Convert Square feet per minute (ft²/min) to Square feet per hour (ft²/h) instantly and accurately.
Conversion Formula
ft²/h = ft²/min × 60
About Square feet per minute
The square foot per minute (ft²/min) equals ≈1.548 × 10⁻³ m²/s, an uncommon transitional unit appearing in some older US industrial furnace design charts and heat-treatment process sheets where holding times are expressed in minutes. 1 ft²/min = 60 ft²/h = 0.09290304/60 m²/s ≈1.548 × 10⁻³ m²/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.
