Input

Note: Assumes 50 Ω system. Input voltages are RMS values.

Output

mW

Equations

\[ P_{dBm} = 10 \log_{10}(P_{mW}) \]

\[ P_{dBW} = 10 \log_{10}(P_{W}) \]

\[ P_{mW} = 10^{\tfrac{P_{dBm}}{10}} \]

\[ P_{W} = 10^{\tfrac{P_{dBW}}{10}} \]

\[ P_{dBW} = P_{dBm} - 30 \]

Where:
  • \( P_{dBm} \) = power in decibel-milliwatts
  • \( P_{dBW} \) = power in decibel-watts
  • \( P_{mW} \) = power in milliwatts
  • \( P_{W} \) = power in watts
