The dBm to Watt converter allows you to transform a power expressed in dBm (decibels-milliwatts) into its equivalent value in Watt.
This tool is frequently used in the fields of radio frequency, telecommunications and electronics to evaluate the real strength of a signal.
Formula used
P(W) = 10 (P(dBm)/10) / 1000
Or :
P(W) = power in Watt
P(dBm) = power in dBm
Explanation
The dBm is a logarithmic unit used to express power relative to 1 milliwatt.
The conversion to Watt is based on the exponential relationship between the two units.
Each increase of 10 dBm corresponds to a multiplication of the power by 10 in Watt.
So, 0 dBm is 1 mW (0.001 W), while 30 dBm is 1 W.
Calculation example
For a power of 20 dBm :
P(W) = 10 (20/10) / 1000 = 100 / 1000 = 0.1 W
So, a signal of 20 dBm corresponds to a power of 0.1 Watt.
Benefits and Use
- Facilitates quick conversion between dBm and Watt for RF measurements.
- Useful for analyzing the output power of amplifiers and transmitters.
- Allows adjustment of power levels in communications systems.
- Essential for RF engineers, telecommunications technicians and electronic circuit designers.
