Conversion Formula
The formula to convert dbm to watts is Watts = 10^((dBm – 30) / 10). It works because dBm is a logarithmic measure of power relative to 1 milliwatt. Subtracting 30 from dBm adjusts the scale to watts, and raising 10 to this power gives the watt value.
For example, at 55 dBm: (55 – 30) / 10 = 2.5; then, 10^2.5 = 316.23 watts. This method converts the logarithmic dBm measurement into a linear watt measurement, making power levels comparable in real-world units.
Conversion Example
- Convert 45 dBm to watts:
- (45 – 30) / 10 = 1.5
- 10^1.5 = 31.62 watts
- Convert 60 dBm to watts:
- (60 – 30) / 10 = 3
- 10^3 = 1000 watts
- Convert 50 dBm to watts:
- (50 – 30) / 10 = 2
- 10^2 = 100 watts
- Convert 70 dBm to watts:
- (70 – 30) / 10 = 4
- 10^4 = 10,000 watts
- Convert 35 dBm to watts:
- (35 – 30) / 10 = 0.5
- 10^0.5 = 3.16 watts
