Conversion Formula

m²/h = in²/h × 0.00064516

About Square inches per hour

The square inch per hour (in²/h) equals ≈1.792 × 10⁻⁷ m²/s, used in US heat-transfer handbooks and HVAC insulation specifications. Pre-SI tables for building insulation board and refractory brick often list thermal diffusivity in in²/h. Firebrick: ≈3.5 in²/h; rigid foam: ≈0.8-1.2 in²/h. 1 in²/h = 0.00064516/3600 m²/s.

About Square metres per hour

The square metre per hour (m²/h) equals 1/3600 m²/s ≈2.778 × 10⁻⁴ m²/s, used in large-scale geotechnical and civil engineering analyses. Soil consolidation models and groundwater thermal plume simulations often use m²/h because the full diffusion process unfolds over hours to days. 1 m²/h = 10 000 cm²/h ≈ 2.778 × 10⁻⁴ m²/s.
