Convert Milliwatt per square metre to Thermochemical kilocalorie per hour per square metre
Convert Milliwatt per square metre (mW/m²) to Thermochemical kilocalorie per hour per square metre (kcal(th)/(h·m²)) instantly and accurately.
Conversion Formula
kcal(th)/(h·m²) = mW/m² × 0.0008604206501
About Milliwatt per square metre
The milliwatt per square metre (mW/m²) equals 10⁻³ W/m². Relevant in geothermal surveys: global average continental heat flux ≈ 65 mW/m², oceanic ≈ 101 mW/m². Used in building physics for quantifying very small heat leakage through ultra-high-performance insulation. 1 mW/m² = 10⁻³ W/m² = 1 erg/(s·cm²).
About Thermochemical kilocalorie per hour per square metre
The thermochemical kilocalorie per hour per square metre (kcal(th)/(h·m²)) equals 4184/3600 ≈ 1.1622 W/m² (1 kcal(th) = 4184 J; 1 h = 3600 s). Used in older continental European and Soviet-era building physics standards for wall and roof heat loss calculations. 1 kcal(th)/(h·m²) ≈ 1.1622 W/m².
