Convert Square inches per hour to Square centimetres per second
Convert Square inches per hour (in²/h) to Square centimetres per second (cm²/s) instantly and accurately.
Conversion Formula
cm²/s = in²/h × 0.001792111111
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.
About Square centimetres per second
The square centimetre per second (cm²/s) equals 1 × 10⁻⁴ m²/s and is the CGS unit for thermal diffusivity, sometimes called the stokes by analogy with kinematic viscosity. Pre-SI thermophysics literature and many older reference databases list values in cm²/s: iron ≈0.18 cm²/s; aluminium ≈0.84 cm²/s; water ≈1.4 × 10⁻³ cm²/s. 1 cm²/s = 1 × 10⁻⁴ m²/s.
