17 dBm equals approximately 0.05 watts.
Converting 17 dBm to watts involves using the formula that relates logarithmic decibel-milliwatts to linear watts. Since dBm is a measure of power relative to 1 milliwatt, converting it to watts requires exponentiating the value after adjusting for the decibel scale. Specifically, the formula is Watts = 10^((dBm – 30) / 10).
Conversion Result
17 dBm is approximately 0.0501 watts based on the calculation.

Conversion Formula
The conversion from dbm to watts uses the formula: Watts = 10^((dBm – 30) / 10). This comes from the fact that dBm is a logarithmic measurement of power relative to 1 milliwatt. By subtracting 30, we shift from milliwatts to watts, then raise 10 to that power to get linear value. For example, for 17 dBm:
- Subtract 30 from 17: 17 – 30 = -13
- Divide by 10: -13 / 10 = -1.3
- Raise 10 to -1.3: 10^-1.3 ≈ 0.0501 watts
Conversion Example
Suppose we want to convert 25 dBm into watts. Here’s how it works:
- Subtract 30: 25 – 30 = -5
- Divide by 10: -5 / 10 = -0.5
- Calculate 10^-0.5: approximately 0.3162 watts
Similarly, for 10 dBm:
- Subtract 30: 10 – 30 = -20
- Divide by 10: -20 / 10 = -2
- Calculate 10^-2: 0.01 watts

Conversion Definitions
dbm
dbm is a logarithmic measure of power level relative to 1 milliwatt, expressed in decibels. It indicates the strength of a signal in relation to a baseline, making comparisons easier across different power levels in electronic and radio systems.
watts
Watts are a standard unit of power representing the rate of energy transfer. It quantifies how much energy is used or produced per second, and is used across electrical, mechanical, and thermal systems to measure power output or consumption.
Conversion FAQs
What is the easiest way to convert 17 dBm to watts without a calculator?
Using the formula Watts = 10^((dBm – 30)/10), you can estimate the power by calculating the exponent first, then raising 10 to that power. For quick approximations, understanding the logarithmic nature helps in mentally estimating the watt value.
Does the conversion from 17 dBm to watts depend on frequency or is it fixed?
The conversion from dBm to watts is fixed mathematically and does not depend on frequency. However, in practical applications like radio transmission, the effective power may vary with frequency due to system efficiencies and antenna characteristics.
Why is 17 dBm considered a moderate power level?
Because 17 dBm roughly equals 0.05 watts, it falls into a range used in wireless devices, such as Wi-Fi or Bluetooth transmitters, where this power level balances coverage and battery life, not too high or too low for typical portable applications.
Can I convert watt values back to dBm easily?
Yes, by using the reverse formula: dBm = 10 * log10(Watts) + 30. This allows you to convert watt measurements back into the decibel-milliwatt scale for comparison or specification purposes.
