Instant conversion with high precision. dBm to Watts: W = 10^((dBm-30)/10). Ideal for RF link budgets.
Compute mW/cm² given distance, frequency, and EIRP. Essential for RF exposure & safety compliance.
FSPL (dB) formula: 20·log10(d) + 20·log10(f) + 32.44. Evaluate signal attenuation over distance.
Upload hundreds of rows, each an independent RF calculation. Export results to CSV for documentation.
Power (W) = 10^((dBm - 30)/10). Example: 30 dBm = 1 W, 20 dBm = 0.1 W, 40 dBm = 10 W. The calculator does this automatically.
Power Density (mW/cm²) = (EIRP in mW) / (4·π·r²) where r is distance in cm. Or using dBm: PD = 10^(PdBm/10) / (4·π·(r*100)²). This tool handles conversions.
FSPL estimates signal loss between antennas in ideal conditions. Formula: 20·log10(d_km) + 20·log10(f_MHz) + 32.44 dB. Critical for wireless link budgets.
