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 inches per hour
The square inch per hour (in²/h) equals ≈1.792 × 10⁻⁷ m²/s, used in US heat-transfer handbooks and HVAC insulation specifications. Pre-SI tables for building insulation board and refractory brick often list thermal diffusivity in in²/h. Firebrick: ≈3.5 in²/h; rigid foam: ≈0.8-1.2 in²/h. 1 in²/h = 0.00064516/3600 m²/s.
