## Core Conversion Equations
1. dBm to Watts: P(W) = 10^((dBm - 30) / 10)
2. Watts to dBm: dBm = 10 * log10(P(W)) + 30
3. RMS Voltage at Z0: V_rms = sqrt( P(W) * Z0 )
4. Peak-to-Peak Voltage: V_pp = 2 * sqrt(2) * V_rms
5. dBµV at 50Ω: dBµV = dBm + 107
6. Thermal Noise Limit (290K, 1Hz): -174 dBm/Hz
7. EIRP: EIRP(dBm) = PTX(dBm) - Loss(dB) + GTX(dBi)
8. ERP: ERP = EIRP - 2.15 dB
9. FSPL: FSPL(dB) = 20*log10(d_km) + 20*log10(f_MHz) + 32.44
10. Power Density: S = EIRP / (4 * pi * R^2)
