Convert Square inches per minute to Square metres per minute
Convert Square inches per minute (in²/min) to Square metres per minute (m²/min) instantly and accurately.
Conversion Formula
m²/min = in²/min × 0.00064516
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 metres per minute
The square metre per minute (m²/min) equals 1/60 m²/s ≈0.01667 m²/s, a non-standard unit seen in some process-engineering contexts where heat soak times are measured in minutes rather than seconds. Nuclear fuel rod thermal analysis and large refractory furnace lining design occasionally cite diffusivity in m²/min. 1 m²/min = 1/60 m²/s ≈ 6000 cm²/s.
