Convert Square millimetres per minute to Square feet per second
Convert Square millimetres per minute (mm²/min) to Square feet per second (ft²/s) instantly and accurately.
Conversion Formula
ft²/s = mm²/min × 1.793985069e-7
About Square millimetres per minute
The square millimetre per minute (mm²/min) equals 1/60 000 000 m²/s. It appears in material testing standards where thermal diffusivity of polymers and composites is measured over minute-scale heating pulses. ASTM and ISO laser-flash methods sometimes report in mm²/min as an intermediate step. 1 mm²/min = 1e-6/60 m²/s ≈ 1.667 × 10⁻¸ m²/s.
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.
