Power Density Converter
Convert electric field strength to power density (W/m² or mW/cm²) for far-field radiated emissions.
Use this when: You are evaluating RF exposure, antenna effective radiated power, or comparing to SAR and safety limits.
Key formula
S (W/m²) = E² / 377Example: Enter 377 V/m → 377 W/m²
Valid for far field / plane wave conditions only.
