Conversion Formula
The formula to convert dBm to watts is Watts = 10^((dBm – 30) / 10). It works by converting the logarithmic dBm value into a linear scale. For example, with 47.8 dBm, subtract 30 to get 17.8, then raise 10 to this power, resulting in approximately 62.59 watts. This calculation translates the dBm value into actual power.
Conversion Example
- Convert 40 dBm to watts:
- Subtract 30 from 40: 40 – 30 = 10
- Calculate 10^10/10: 10^1 = 10
- Result: 10 watts
- Convert 50 dBm to watts:
- 50 – 30 = 20
- 10^20/10: 10^2 = 100
- Result: 100 watts
- Convert 45 dBm to watts:
- 45 – 30 = 15
- 10^15/10: 10^1.5 ≈ 31.62
- Result: approximately 31.62 watts
- Convert 60 dBm to watts:
- 60 – 30 = 30
- 10^30/10: 10^3 = 1000
- Result: 1000 watts
- Convert 47.8 dBm to watts:
- 47.8 – 30 = 17.8
- 10^17.8/10 ≈ 62.59
- Result: about 62.59 watts

Conversion Definitions
dbm
dbm is a logarithmic measurement expressing power levels relative to 1 milliwatt, where 0 dBm equals 1 milliwatt. It simplifies comparisons of signal strengths in telecommunications, with each 10 dB increase indicating tenfold power increase.
watts
Watts are a unit of power representing the rate of energy transfer, used in electrical and mechanical contexts. It quantifies the actual amount of power in a system, with 1 watt equaling 1 joule per second, providing an absolute measurement of energy flow.
Conversion FAQs
How accurate is the conversion from dBm to watts?
The conversion from dBm to watts relies on the formula Watts = 10^((dBm – 30) / 10), which is mathematically precise for power levels. However, practical measurements can vary slightly due to equipment calibration and environmental factors.
Can I convert any dBm value to watts using this method?
Yes, the formula applies to any dBm value, positive or negative, enabling conversion across a wide range of power levels. Just substitute the specific dBm value into the formula for an accurate result.
Why do dBm and watts differ in their usage?
dbm provides a logarithmic scale suitable for comparing signal strengths over large ranges, making it convenient in telecommunications. Watts give an absolute measure of actual power, essential for engineering and practical application purposes.
What happens if I input a negative dBm value?
Negative dBm values indicate power levels below 1 milliwatt, and the conversion formula still works. For example, -10 dBm equals approximately 0.1 watts, showing the lower power level in a linear scale.
