Elara Bennett5 dBm equals approximately 3.16 milliwatts (mW).
To convert 5 dBm to mW, we use the formula: mW = 10^((dBm) / 10). So, plugging in 5, we get 10^(5/10) = 10^0.5, which equals roughly 3.16 mW. This conversion shows how power levels in decibel-milliwatts relate to actual milliwatt values by applying the logarithmic scale.
What is 5 dBm in milliwatts?
The value 5 dBm in milliwatts is about 3.16 mW. Decibel-milliwatts are logarithmic units representing power ratios, so converting to milliwatts involves exponentiating 10 to the power of dBm divided by 10. This transforms the logarithmic measurement into a linear power measurement.

Conversion Formula
The conversion from dbm to mw uses the formula: mW = 10^(dBm / 10). It works because decibel-milliwatts are logarithmic measurements of power. Dividing dBm by 10 gives the exponent, and raising 10 to this power calculates the actual power in mw. For example, 5 dBm: 10^(5/10) = 10^0.5 ≈ 3.16 mw.
Conversion Example
- Convert 10 dBm:
- Divide 10 by 10: 10/10 = 1.
- Calculate 10^1 = 10 mw.
- So, 10 dBm equals 10 milliwatts.
- Convert -10 dBm:
- Divide -10 by 10: -10/10 = -1.
- Calculate 10^(-1) = 0.1 mw.
- Therefore, -10 dBm equals 0.1 milliwatts.
- Convert 0 dBm:
- Divide 0 by 10: 0/10 = 0.
- Calculate 10^0 = 1 mw.
- Thus, 0 dBm equals 1 milliwatt.
- Convert 20 dBm:
- Divide 20 by 10: 20/10 = 2.
- Calculate 10^2 = 100 mw.
- So, 20 dBm equals 100 milliwatts.

Conversion Definitions
dbm
dbm, or decibel-milliwatts, measures power levels in logarithmic scale relative to 1 milliwatt, indicating signal strength or power output; every 10 dBm increase multiplies power roughly tenfold in milliwatts.
mw
mw, or milliwatts, is a unit of power measurement representing one-thousandth of a watt, used in electronics and communication to quantify signal and power levels in a linear, straightforward way.
Conversion FAQs
How does changing the dBm value affect the mw result?
Increasing dBm by 10 increases mw tenfold, while decreasing by 10 reduces mw to one-tenth. This exponential relationship means small dBm changes lead to large mw differences, showing the logarithmic nature of the measurement.
Can I convert dBm to mw manually without tools?
Yes, by applying the formula: mw = 10^(dBm / 10). You simply divide the dBm value by 10, then raise 10 to this power, which can be done with a calculator or logarithm tables for accuracy.
What practical applications use dBm to mw conversions?
This conversion is used in RF engineering, wireless communication, antenna design, and signal testing, where understanding actual power levels in milliwatts helps in designing and troubleshooting systems.
Why is dBm preferred over direct watt measurements?
dBm simplifies managing very large or small power levels by compressing them into a logarithmic scale, making it easier to compare, analyze, and communicate power differences without dealing with cumbersome numbers.
