This tool converts a Current value in Amps or Amperes to its equivalent Power value in dBm.
- Current (I). Select units: A/mA/μA/nA/pA
- Impedance (Z). The default value is 50 ohm although it can be changed to any value
PdBm = 20*Log10(I) + 10*Log10(Z) + 30
For a current value of 1 Amp and Impedance of 50 ohm, the equivalent power PdBm is 47 dBm.
For the same value of current and a resistance of 75 ohm, PdBm is 48.75 dBm.
