The result of converting 7 dbm to mw is approximately 5.01 milliwatts.
To convert from dbm to mw, you use the formula mw = 10^(dbm/10). For 7 dbm, divide 7 by 10 to get 0.7, then raise 10 to that power, resulting in 10^0.7, which equals about 5.01 mw. This calculation translates a logarithmic power level into a linear watt measurement.
Conversion Result
7 dbm equals approximately 5.01 mw. This means that a signal with a power level of 7 decibels relative to 1 milliwatt has about 5.01 milliwatts of actual power.

Conversion Formula
The conversion from dbm to mw uses the formula mw = 10^(dbm/10). This works because decibels are logarithmic, meaning each 10 dB increase represents ten times the power. By dividing the dbm value by 10, we get the exponent, which we then raise 10 to, to find mw. For example, for 7 dbm: 10^(7/10) = 10^0.7 ≈ 5.01 mw.
Conversion Example
- Convert 10 dbm to mw:
- Divide 10 by 10 to get 1.
- Calculate 10^1, which equals 10 mw.
- Convert 0 dbm to mw:
- Divide 0 by 10 to get 0.
- Calculate 10^0, which equals 1 mw.
- Convert -10 dbm to mw:
- Divide -10 by 10 to get -1.
- Calculate 10^-1, which equals 0.1 mw.

Conversion Definitions
dbm
dbm stands for decibels relative to 1 milliwatt, measuring power levels logarithmically. It compares a signal’s power to 1 mw, where each 10 dB increase indicates ten times more power, making it a common unit in radio and telecommunications for signal strength.
mw
Milliwatt (mw) is a unit of power equal to one-thousandth of a watt. It quantifies the actual energy transfer rate in electronic devices, with higher mw indicating stronger signals or greater power output in wireless communication and audio systems.
Conversion FAQs
Why does converting dbm to mw involve raising 10 to a power?
The relationship uses logarithms because decibels are logarithmic, meaning each 10 dB change multiplies power by ten. Raising 10 to dbm/10 converts the logarithmic value back to a linear scale, giving the exact mw power level.
Can I convert any dbm value into mw using the same formula?
Yes, the formula mw = 10^(dbm/10) works for all real numbers dbm, whether positive or negative. It provides a precise way to translate between logarithmic and linear power units across a wide range of values.
How does negative dbm relate to mw?
Negative dbm indicates power levels below 1 mw. For example, -10 dbm translates to 0.1 mw, showing a weaker signal. The formula accounts for this, producing smaller mw values as dbm becomes more negative.
