Convert Square millimetres per second to Square inches per minute
Convert Square millimetres per second (mm²/s) to Square inches per minute (in²/min) instantly and accurately.
Conversion Formula
in²/min = mm²/s × 0.093000186
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 inches per minute
The square inch per minute (in²/min) equals ≈1.075 × 10⁻⁵ m²/s, found in US military and aerospace specifications for thermal protection materials and ablative heat shields. Some NASA technical reports on reentry vehicle TPS (Thermal Protection System) materials quote diffusivity in in²/min. 1 in²/min = 0.00064516/60 m²/s.
