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.
| dBm | Watt |
|---|---|
| 0 | 1 mW |
| 10 | 10 mW |
| 20 | 100 mW |
| 30 | 1 W |
| 40 | 10 W |
| 50 | 100 W |
| 60 | 1,000 W (1 kW) |
| 70 | 10,000 W (10 kW) |
| 80 | 100,000 W (100 kW) |
