Exact Mathematical Derivation for -26 dBm
Step 1: P(mW) = 10^(-26 / 10) = 10^(-2.60) = 0.003 mW
Step 2: P(W) = 0.003 mW ÷ 1,000 = 2.5119e-6 Watts
Step 3: V_RMS (@ 50Ω) = √(2.512e-6 W × 50 Ω) = 0.0112 V RMS (81.0 dBμV)
Step 2: P(W) = 0.003 mW ÷ 1,000 = 2.5119e-6 Watts
Step 3: V_RMS (@ 50Ω) = √(2.512e-6 W × 50 Ω) = 0.0112 V RMS (81.0 dBμV)

Knowledge Base
Frequently Asked Questions: -26 dBm
Common questions about RF power conversions, negative dBm, and voltage calculations.
-26 dBm is exactly 2.5119e-6 Watts, which equals 0.003 milliwatts (mW).
2.512 µW calculated RF power level. In RF telecommunications, this power level is standard for Low-Power RF Reference.
At 50 Ω impedance, -26 dBm produces 0.0112 V RMS, 0.0158 V Peak, 0.0317 Vpp, and 81.0 dBμV.
-26 dBm equals -56.00 dBW (calculated by subtracting the 30 dB milliwatt offset: -26 − 30).
Doubling the power (+3 dB) increases the level to -23.0 dBm, which equals 5.024e-6 W (0.005 mW).
