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.
About Square centimetres per minute
The square centimetre per minute (cm²/min) equals ≈1.667 × 10⁻⁶ m²/s, a transitional unit seen in older French and Soviet thermal engineering literature. Some food-science papers on heat penetration into frozen products express diffusivity in cm²/min to keep values close to unity. 1 cm²/min = 1e-4/60 m²/s ≈ 1.667 × 10⁻⁶ m²/s.
