Convert Square centimetres per hour to Square inches per minute
Convert Square centimetres per hour (cm²/h) to Square inches per minute (in²/min) instantly and accurately.
Conversion Formula
in²/min = cm²/h × 0.0025833385
About Square centimetres per hour
The square centimetre per hour (cm²/h) equals 1/36 000 000 m²/s. Environmental geophysicists use cm²/h when measuring heat flow in sedimentary rock columns or permafrost layers. Granite has a diffusivity of ≈36 cm²/h; dry sand ≈9 cm²/h. 1 cm²/h = 1e-4/3600 m²/s ≈ 2.778 × 10⁻⁸ 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.
