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.
About Square decimetres per second
The square decimetre per second (dm²/s) equals exactly 0.01 m²/s, a rarely used but exact-ratio metric unit. It is occasionally encountered in European academic papers on molten metals and liquid semiconductors, where diffusivity values in m²/s are small fractions and dm²/s gives more convenient numeric magnitudes. 1 dm²/s = 1e-2 m²/s = 100 cm²/s.
