Convert Square centimetres per minute to Square metres per second
Convert Square centimetres per minute (cm²/min) to Square metres per second (m²/s) instantly and accurately.
Conversion Formula
m²/s = cm²/min × 1.666666667e-6
About Square centimetres per minute
The square centimetre per minute (cm²/min) equals ≈1.667 × 10⁻⁶ m²/s, a transitional unit seen in older French and Soviet thermal engineering literature. Some food-science papers on heat penetration into frozen products express diffusivity in cm²/min to keep values close to unity. 1 cm²/min = 1e-4/60 m²/s ≈ 1.667 × 10⁻⁶ 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.
