Square centimetres per hour (cm²/h)
Square inches per second (in²/s)

Conversion Formula

in²/s = cm²/h × 4.305564167e-5

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 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.
