Convert Square centimetres per minute to Square inches per hour
Convert Square centimetres per minute (cm²/min) to Square inches per hour (in²/h) instantly and accurately.
Conversion Formula
in²/h = cm²/min × 9.3000186
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.
About Square inches per hour
The square inch per hour (in²/h) equals ≈1.792 × 10⁻⁷ m²/s, used in US heat-transfer handbooks and HVAC insulation specifications. Pre-SI tables for building insulation board and refractory brick often list thermal diffusivity in in²/h. Firebrick: ≈3.5 in²/h; rigid foam: ≈0.8-1.2 in²/h. 1 in²/h = 0.00064516/3600 m²/s.
