Samantha NicoleThe conversion of 45 dBm to watts equals approximately 31.62 watts. This means that a signal with 45 dBm has a power level of about 31.62 watts, which is a substantial amount of power in many communication systems.
To explain in details, dBm is a logarithmic measurement of power referenced to 1 milliwatt. The formula to convert dBm to watts is P(watts) = 10^((dBm – 30) / 10). For 45 dBm, subtract 30 to get 15, then raise 10 to the power of 1.5, resulting in roughly 31.62 watts, which shows the linear power equivalent.
Conversion Result
45 dBm is approximately 31.62 watts, indicating a high power level often used in radio transmission and high-power amplifier applications.

Conversion Formula
The formula to convert dBm to watts is P(watts) = 10^((dBm – 30) / 10). This works because dBm is a logarithmic representation of power, where each 10 dB increase signifies a tenfold increase in power. By subtracting 30, we convert dBm to decibels relative to 1 watt, then convert back to linear watts.
For example, with 45 dBm: subtract 30 to get 15, then raise 10 to the power of 1.5. That gives approximately 31.62 watts, which is the linear power equivalent.
Conversion Example
- Convert 50 dBm to watts:
- Subtract 30 from 50: 20
- Calculate 10^20/10 = 10^2 = 100 watts
- Convert 30 dBm to watts:
- Subtract 30 from 30: 0
- Calculate 10^0 = 1 watt
- Convert 60 dBm to watts:
- Subtract 30: 30
- Calculate 10^3 = 1000 watts
- Convert 40 dBm to watts:
- Subtract 30: 10
- Calculate 10^1 = 10 watts
- Convert 55 dBm to watts:
- Subtract 30: 25
- Calculate 10^2.5 ≈ 316.23 watts
