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 second
The square inch per second (in²/s) equals 6.4516 × 10⁻⁴ m²/s, used in high-speed thermal analyses such as ballistic impact heating, explosive detonation studies, and rapid induction heating of steel billets. Values for high-conductivity copper alloys reach ≈1-2 in²/s; for mild steel ≈0.3 in²/s. 1 in²/s = 0.00064516 m²/s = 3600 in²/h.
