This tool converts Power in dBm to a percentage (%) value.
Converting dBm to a decibel percentage is not a standard conversion, as dBm and percentages are fundamentally different units representing different concepts.
However when a dBm value is compared to a reference power value in dBm it can be expressed as a percentage.
Enter
- Power in dBm
- Reference power in dBm
The tool will calculate the percent value
Formula
P = 10(PdBm/10) /1000
P = 10(PrefdBm/10) /1000
Percent (%) = (P/Pref)*100
where
- P is the linear power
- Pref is the linear reference power
Example Calculations
- A power level of -10 dBm and Reference power of 0 dBm converts to 10%
- Input power of 0 dBm and reference power of -20 dBm converts to 10,000%
