Exact RatioAbout Milliwatt per Square Centimeter (mW/cm²)
A metric irradiance unit equal to 10 watts per square meter (1 mW/cm² = 10 W/m²).
History: Widely used in laboratory photochemistry, UV disinfection, and medical phototherapy.
Common Uses: UV-C germicidal lamp irradiance verification, dental polymer curing lights, dermatology PUVA phototherapy.
About Watt per Square Meter (W/m²)
The SI coherent derived unit of radiant flux received by a surface per unit area (1 W/m²). Distinct from photometric illuminance (lux) as it integrates across all optical wavelengths without human eye photopic weighting.
History: Standardized in SI radiometry; fundamental metric for the solar constant (~1,361 W/m² at top of atmosphere).
Common Uses: Meteorology, solar power plant pyranometer sensors, UV index monitoring, radiative heating.
❓ Frequently Asked Questions
How many Watts per Square Meter are in 1 Milliwatt per Square Centimeter?
