The conversion of 27 dBm to watts results in approximately 0.5012 watts.
To convert 27 dBm to watts, we use the formula that relates decibel-milliwatts to watts: watts = 10^((dBm – 30)/10). This formula converts the logarithmic dBm value into a linear watt measurement, providing an exact power level in watts based on the dBm input.

Conversion Formula
The formula for converting dbm to watts is watts = 10^((dBm – 30)/10). This works because dBm is a logarithmic measurement of power relative to 1 milliwatt. By subtracting 30, we shift the scale from milliwatts to watts and exponentiate to find the actual power. For example, with 27 dBm:
- Subtract 30: 27 – 30 = -3
- Divide by 10: -3 / 10 = -0.3
- Calculate 10 to the power of -0.3: 10^-0.3 ≈ 0.5012 watts
Conversion Example
- Suppose we want to convert 20 dBm:
- Subtract 30: 20 – 30 = -10
- Divide by 10: -10 / 10 = -1
- Calculate 10^-1: 0.1 watts
- So, 20 dBm equals 0.1 watts.
- Convert 35 dBm:
- Subtract 30: 35 – 30 = 5
- Divide by 10: 5 / 10 = 0.5
- Calculate 10^0.5: approximately 3.1623 watts
- Therefore, 35 dBm is about 3.1623 watts.
- For 15 dBm:
- Subtract 30: 15 – 30 = -15
- Divide by 10: -15 / 10 = -1.5
- Calculate 10^-1.5: approximately 0.0316 watts
- Thus, 15 dBm equals roughly 0.0316 watts.

Conversion Definitions
dbm
dbm is a logarithmic measurement indicating the power level relative to 1 milliwatt; 0 dBm equals 1 milliwatt, and each increase of 10 dBm multiplies power by ten, used mainly in radio and audio systems to express signal strength.
watts
Watts is an SI unit of power measuring energy transfer per second, used across electrical, mechanical, and thermal systems; it quantifies the rate at which work is done or energy is transferred in a system.
Conversion FAQs
What does 27 dBm mean in terms of power?
27 dBm indicates a power level of about 0.5012 watts, representing a moderate signal strength often used in wireless communications, showing how much energy is being transmitted per second.
Can I convert dBm to watts manually?
Yes, by applying the formula watts = 10^((dBm – 30) / 10), you can convert any dBm value into watts without special tools, which helps in understanding the actual power levels.
Why is the conversion from dBm to watts logarithmic?
Because dBm is based on a logarithmic scale, it simplifies expressing large ranges of power levels; converting back to watts involves exponentiation to linearize the measurement, making calculations more manageable.
