Formula for dBm to Watt Conversion
The dBm to Watt conversion calculator uses the formula:
Watt = 10^(dBm / 10) / 1000
Formula Explanation
This formula converts a power level expressed in dBm (decibels relative to 1 milliwatt) into watts. The dBm value is divided by 10, then used as an exponent of 10, and finally divided by 1000 to convert milliwatts into watts.
Uses of the dBm to Watt Conversion Calculator
- Converting RF signal levels for system design and analysis.
- Evaluating power output in wireless communication systems.
- Designing and testing amplifiers and transmitters.
- Comparing measured dBm values to standard power levels.
- Educational purposes for understanding power unit conversions.
Formula Example
If a signal has a power of 20 dBm:
Watt = 10^(20 / 10) / 1000 = 0.1 W
This means a 20 dBm signal corresponds to 0.1 Watt of power.
