Convert Square metres per hour to Square metres per second
Convert Square metres per hour (m²/h) to Square metres per second (m²/s) instantly and accurately.
Conversion Formula
m²/s = m²/h × 0.0002777777778
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.
About Square metres per second
The square metre per second (m²/s) is the SI unit for thermal diffusivity (α = k / ρc_p). It defines how fast a temperature disturbance propagates through a material. Diamond: ≈5 × 10⁻⁴ m²/s; silver: ≈1.65 × 10⁻⁴ m²/s; aluminium: ≈8.4 × 10⁻⁵ m²/s; iron: ≈1.8 × 10⁻⁵ m²/s; concrete: ≈6 × 10⁻⁷ m²/s; water: ≈1.4 × 10⁻⁷ m²/s. 1 m²/s = 10⁶ mm²/s = 10⁴ cm²/s.
