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 Erg per second per square centimetre

The erg per second per square centimetre (erg/(s·cm²)) equals exactly 10⁻³ W/m² in SI (1 erg = 10⁻⁷ J; 1 cm² = 10⁻⁴ m²). The CGS irradiance unit used in classical electromagnetic theory, astrophysics, and older radiation physics literature. Numerically equal to the milliwatt per square metre. 1 erg/(s·cm²) = 10⁻³ W/m² = 1 mW/m².
