Convert Milliwatt per square centimetre to Celsius Heat Unit per hour per square foot
Convert Milliwatt per square centimetre (mW/cm²) to Celsius Heat Unit per hour per square foot (CHU/(h·ft²)) instantly and accurately.
Conversion Formula
CHU/(h·ft²) = mW/cm² × 1.761101837
About Milliwatt per square centimetre
The milliwatt per square centimetre (mW/cm²) equals exactly 10 W/m² (1 mW = 10⁻³ W; 1 cm² = 10⁻⁴ m²). Widely used in photonics, laser safety standards (IEC 60825), and UV dosimetry. Solar irradiance at Earth's surface ≈ 100 mW/cm². 1 mW/cm² = 10 W/m² = 0.001 W/cm².
About Celsius Heat Unit per hour per square foot
The Celsius heat unit per hour per square foot (CHU/(h·ft²)) equals (9/5)×1055.05585262/(3600×0.09290304) ≈ 5.6783 W/m². The CHU (= 9/5 BTU(IT)) uses a 1 °C temperature interval instead of 1 °F; historically used in UK and Canadian heating engineering. 1 CHU/(h·ft²) ≈ 5.6783 W/m² = (9/5) × BTU(IT)/(h·ft²).
