Convert Square centimetres per second to Square inches per second
Convert Square centimetres per second (cm²/s) to Square inches per second (in²/s) instantly and accurately.
Conversion Formula
in²/s = cm²/s × 0.15500031
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.
About Square inches per second
The square inch per second (in²/s) equals 6.4516 × 10⁻⁴ m²/s, used in high-speed thermal analyses such as ballistic impact heating, explosive detonation studies, and rapid induction heating of steel billets. Values for high-conductivity copper alloys reach ≈1-2 in²/s; for mild steel ≈0.3 in²/s. 1 in²/s = 0.00064516 m²/s = 3600 in²/h.
