Convert Square feet per second to Square metres per second
Convert Square feet per second (ft²/s) to Square metres per second (m²/s) instantly and accurately.
Conversion Formula
m²/s = ft²/s × 0.09290304
About Square feet per second
The square foot per second (ft²/s) equals 0.09290304 m²/s, the imperial base unit for thermal diffusivity analogous to m²/s. It is used in US aerospace engineering and combustion research for highly conductive materials and high-temperature plasmas. Diamond, the most thermally diffusive solid at ≈7 cm²/s, converts to ≈0.0075 ft²/s; silver to ≈0.00167 ft²/s. 1 ft²/s = 3600 ft²/h = 0.09290304 m²/s.
About Square metres per second
The square metre per second (m²/s) is the SI unit for thermal diffusivity (α = k / ρc_p). It defines how fast a temperature disturbance propagates through a material. Diamond: ≈5 × 10⁻⁴ m²/s; silver: ≈1.65 × 10⁻⁴ m²/s; aluminium: ≈8.4 × 10⁻⁵ m²/s; iron: ≈1.8 × 10⁻⁵ m²/s; concrete: ≈6 × 10⁻⁷ m²/s; water: ≈1.4 × 10⁻⁷ m²/s. 1 m²/s = 10⁶ mm²/s = 10⁴ cm²/s.
