About Square millimetres per second

The square millimetre per second (mm²/s) equals 1 × 10⁻⁶ m²/s and is the standard unit in materials engineering and the laser-flash diffusivity method (ASTM E1461, ISO 22007-4). Metals span roughly 2-180 mm²/s; polymers 0.07-0.2 mm²/s; ceramics 0.3-10 mm²/s. Numerically identical to the kinematic viscosity unit (cSt) in SI context. 1 mm²/s = 1 × 10⁻⁶ m²/s.

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.
