Power ↔ dBm calculator
Convert linear optical power to dBm and dBW.
Category: Unit Converters
Formula: dBm = 10·log₁₀(P/1 mW)
Inputs
| Input | Parameter | Unit | Default |
|---|---|---|---|
| Power | P | mW | 1 |
Result with the default inputs
- Power: 1 mW
- Power: 1000 µW
- Power: 0.001 W
- dBm: 0
- dBW: -30
Open it with your own values: put each input in the address as a parameter, for example /calculators/power-dbm?P=1. A unit other than the listed one goes in <parameter>_unit.
