Convert Square feet per hour to Square metres per hour
Convert Square feet per hour (ft²/h) to Square metres per hour (m²/h) instantly and accurately.
Conversion Formula
m²/h = ft²/h × 0.09290304
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 metres per hour
The square metre per hour (m²/h) equals 1/3600 m²/s ≈2.778 × 10⁻⁴ m²/s, used in large-scale geotechnical and civil engineering analyses. Soil consolidation models and groundwater thermal plume simulations often use m²/h because the full diffusion process unfolds over hours to days. 1 m²/h = 10 000 cm²/h ≈ 2.778 × 10⁻⁴ m²/s.
