Watt Result
To convert dBm (decibel-milliwatt) to watt, you can use the following formula:
Watt = 10^(dBm/10) / 1000
Here, dBm is the power level in decibels relative to 1 milliwatt (mW).
For example, if you have a power level of -10 dBm, the calculation would be:
Watt = 10^(-10/10) / 1000
= 0.1 / 1000
= 0.0001 W
So, -10 dBm is equivalent to 0.0001 watt or 100 microwatts.
Here’s a table with some examples of dBm to watt conversions:
As you can see from the table, as the power level increases by 10 dBm, the power output increases by a factor of 10. For example, 0 dBm is equivalent to 1 milliwatt (mW), while 10 dBm is equivalent to 10 milliwatts, and 20 dBm is equivalent to 100 milliwatts.
