Amps to dBm Converter
Use this tool to convert current (in amps or milliamps) to dBm and watts based on impedance. The calculation assumes DC current or an RMS current magnitude in a purely resistive or matched load; phase and power factor are not modeled.
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.
