📡 RF Power Converter

Convert between dBm, dBW, Watts, dBµV, and dBmV. All fields update automatically. Assumes 50 Ω impedance for voltage conversions.

Power Units

dBm: decibels relative to 1 mW

dBW: decibels relative to 1 W

Watts: W

Voltage Units (for 50 Ω)

dBµV: decibels relative to 1 µV

dBmV: decibels relative to 1 mV

📐 Conversion Equations

dBm ↔ Watts: P(W) = 10^{((dBm‑30)/10)} dBm = 10·log₁₀(P(W)) + 30

dBW ↔ Watts: P(W) = 10^(dBW/10) dBW = 10·log₁₀(P(W))

dBm ↔ dBW: dBW = dBm – 30 dBm = dBW + 30

dBµV (50 Ω): dBµV = dBm + 107 (since 10·log₁₀(50) ≈ 17)

dBmV (50 Ω): dBmV = dBm + 47

From voltage to power (50 Ω): V_rms = 10^{((dBµV‑120)/20)} volts P = V²/50
