The conversion of 37 dBm to watts is approximately 5.01 watts.
To convert from decibel-milliwatts (dBm) to watts, you need to understand that 0 dBm equals 1 milliwatt (mW). The formula involves exponentiating 10 to the power of (dBm divided by 10), then converting milliwatts to watts by dividing by 1000. For 37 dBm, this calculation yields about 5.01 watts.
Conversion Result and Explanation
37 dBm equals roughly 5.01 watts. This conversion uses the logarithmic relationship where each increase of 10 dBm represents a tenfold increase in power. The calculation involves converting the dBm value to milliwatts and then to watts, giving a clear measure of power in standard units.

Conversion Formula
The formula to convert dbm to watts is: watts = 10^(dBm / 10) / 1000. This works because dBm is a logarithmic measurement of power relative to 1 milliwatt. By exponentiating 10 to the power of dBm divided by 10, you get milliwatts, then dividing by 1000 converts to watts. For example, 37 dBm: 10^(37/10) = 10^3.7 ≈ 5011.87 mW, divided by 1000 equals about 5.01 watts.
Conversion Example
- Convert 20 dBm to watts:
- Calculate 10^(20/10) = 10^2 = 100 mW
- Divide by 1000 to get watts: 100 / 1000 = 0.1 W
- Convert 50 dBm:
- 10^(50/10) = 10^5 = 100,000 mW
- Divide by 1000: 100,000 / 1000 = 100 W
- Convert 10 dBm:
- 10^(10/10) = 10^1 = 10 mW
- Divide by 1000: 10 / 1000 = 0.01 W
- Convert 45 dBm:
- 10^(45/10) = 10^4.5 ≈ 31,622.78 mW
- Divide by 1000: 31,622.78 / 1000 ≈ 31.62 W
- Convert 15 dBm:
- 10^(15/10) = 10^1.5 ≈ 31.62 mW
- Divide by 1000: 31.62 / 1000 ≈ 0.0316 W
