Samantha Nicole5 dBm equals approximately 3.16 milliwatts (mW).
To convert from dBm to mW, you use the formula mW = 10^(dBm/10). This means that each increase of 10 dBm multiplies the power in mW by 10. For 5 dBm, dividing 5 by 10 gives 0.5, and raising 10 to the 0.5 power results in about 3.16 mW.
Conversion Calculation
In converting 5 dBm to mW, the key formula is mW = 10^(dBm/10). This formula works because dBm is a logarithmic measure of power relative to 1 milliwatt. The exponentiation converts the logarithmic value back to a linear power measurement. For example, for 5 dBm:
- Divide 5 by 10, resulting in 0.5.
- Calculate 10 raised to the 0.5 power, which equals approximately 3.16.
- Therefore, 5 dBm is about 3.16 mW.

Conversion Formula
The formula to convert dBm to mW is mW = 10^(dBm/10). It is based on the logarithmic nature of dBm, which measures power relative to 1 mW. Dividing the dBm value by 10 gives the exponent, and raising 10 to that power transforms the logarithmic value into a linear power measure. For example, 10^(5/10) = 10^0.5 = 3.16 mW.
Conversion Example
- Convert 10 dBm to mW:
- Divide 10 by 10, which equals 1.
- Calculate 10^1, which is 10.
- Result: 10 dBm equals 10 mW.
- Convert -10 dBm to mW:
- -10 divided by 10 equals -1.
- Calculate 10^-1, which is 0.1.
- Result: -10 dBm equals 0.1 mW.
- Convert 0 dBm to mW:
- 0 divided by 10 equals 0.
- Calculate 10^0, which is 1.
- Result: 0 dBm equals 1 mW.
- Convert 20 dBm to mW:
- 20 divided by 10 equals 2.
- Calculate 10^2, which is 100.
- Result: 20 dBm equals 100 mW.

Conversion Definitions
dbm
dbm is a logarithmic measurement of power relative to 1 milliwatt, used mainly in radio, telecommunications, and audio systems to express signal strength. Every 10 dBm increase multiplies power in mW by 10, providing a compact way to compare levels.
mw
mW, or milliwatt, is a unit of power equal to one thousandth of a watt. It quantifies the rate of energy transfer, often used in electronics, radio, and signal processing to specify power levels of devices and signals in small-scale applications.
Conversion FAQs
What is the formula to convert 5 dBm to mW?
The formula is mW = 10^(dBm/10). For 5 dBm, it involves dividing 5 by 10 to get 0.5, then calculating 10 raised to 0.5, which results in approximately 3.16 mW.
Can I convert a negative dBm value to mW?
Yes, negative dBm values represent power levels below 1 mW. To convert, divide the negative value by 10, then raise 10 to that exponent. For example, -10 dBm becomes 0.1 mW.
Does increasing dBm always mean increasing mW?
Yes, because the relationship is logarithmic, each increase of 10 dBm multiplies the power by 10, so higher dBm always corresponds to higher mW.
Is 5 dBm considered a strong signal?
In many applications, 5 dBm is moderate power, suitable for short-range wireless communication or low-power transmitters, but it is not very high compared to signals like 20 dBm or more.
