The conversion of 0 dBm to milliwatts (mw) results in exactly 1 mw.
Table of Contents
This happens because 0 dBm is the reference point where the power level equals 1 milliwatt. The dBm scale measures power relative to 1 mw on a logarithmic scale, so a value of 0 dBm directly translates to 1 mw, serving as the baseline for other conversions.
Conversion Result
0 dBm is equal to 1 milliwatt.

Conversion Formula
The formula to convert from dBm to milliwatts is mw = 10^(dBm/10). This formula works because dBm is a logarithmic measure of power relative to 1 mw. By dividing the dBm value by 10, we get the exponent, then raising 10 to this power yields the mw value. For example, 10 dBm equals 10^(10/10) = 10^1 = 10 mw.
Conversion Example
- Convert 10 dBm to mw:
- Divide 10 by 10: 10/10 = 1
- Calculate 10^1: 10^1 = 10 mw
- Convert -10 dBm to mw:
- Divide -10 by 10: -10/10 = -1
- Calculate 10^-1: 10^-1 = 0.1 mw
- Convert 20 dBm to mw:
- Divide 20 by 10: 20/10 = 2
- Calculate 10^2: 10^2 = 100 mw
- Convert -20 dBm to mw:
- Divide -20 by 10: -20/10 = -2
- Calculate 10^-2: 10^-2 = 0.01 mw

Conversion Definitions
dbm
dbm is a logarithmic measurement of power relative to 1 milliwatt, expressed in decibels. It indicates the power level of signals or devices, where 0 dBm equals 1 mw, and each 10 dBm increase represents a tenfold increase in power.
mw
Milliwatt (mw) is a unit of power equal to one-thousandth of a watt. It quantifies the rate of energy transfer in electrical signals and is used in electronics to measure low power levels, making it suitable for small devices and communication systems.
Conversion FAQs
What does 0 dBm mean in terms of actual power?
0 dBm indicates a power level of exactly 1 milliwatt, representing a standard reference point in signal measurement. It is commonly used as a baseline to compare other power levels in electronic and radio frequency applications.
Can I convert dBm to mw manually?
Yes, by applying the formula mw = 10^(dBm/10). Input your dBm value into the exponent, then raise 10 to that power. This calculation converts the logarithmic dBm value into a linear mw measurement, useful for practical power assessments.
What is the significance of the 10-based exponential in the formula?
The base-10 exponential reflects the logarithmic nature of the dBm scale, where each 10 dBm increase correlates with a tenfold power increase. It simplifies the process of moving between logarithmic and linear power units.
How accurate are the conversions at extreme dBm values?
The formula remains precise across a wide range of values, but at very high or low extremes, measurement inaccuracies in the original dBm or device limitations might affect the exact mw calculated. Always consider calibration for critical applications.
