Convert Square inches per second to Square feet per minute
Convert Square inches per second (in²/s) to Square feet per minute (ft²/min) instantly and accurately.
Conversion Formula
ft²/min = in²/s × 0.4166666667
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.
About Square feet per minute
The square foot per minute (ft²/min) equals ≈1.548 × 10⁻³ m²/s, an uncommon transitional unit appearing in some older US industrial furnace design charts and heat-treatment process sheets where holding times are expressed in minutes. 1 ft²/min = 60 ft²/h = 0.09290304/60 m²/s ≈1.548 × 10⁻³ m²/s.
