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.

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.
