Amps to dBm Converter

Use this tool to convert current (in amps or milliamps) to dBm and watts based on impedance.

Ω
Result: 0 dBm
Result: 0 W

Conversion Steps:

1. Watts: P[W] = I² × R

2. Milliwatts: P[mW] = P[W] × 1000

3. dBm: 10 × log₁₀(P[mW])

Common Reference Points:

  • 141.4 mA @ 50Ω = 30 dBm (1W)
  • 44.7 mA @ 50Ω = 20 dBm (100mW)
  • 14.14 mA @ 50Ω = 10 dBm (10mW)

This tool helps with:

  • Performing RF power calculations when measuring current through known impedances.

  • Converting current measurements to RF power values in testing setups.

  • Verifying power levels from current measurements in 50Ω systems.
