Convert Nanowatt per square metre to Milliwatt per square centimetre
Convert Nanowatt per square metre (nW/m²) to Milliwatt per square centimetre (mW/cm²) instantly and accurately.
Conversion Formula
mW/cm² = nW/m² × 1.000000000e-10
About Nanowatt per square metre
The nanowatt per square metre (nW/m²) equals 10⁻⁹ W/m². Used in astrophysics and cosmology for quantifying extremely weak radiation fields, such as cosmic microwave background intensity and residual thermal emission from near-absolute-zero objects. Relevant in precision cryogenic sensor calibration. 1 nW/m² = 10⁻⁹ W/m² = 10³ pW/m².
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.
