mW to dBm Conversion
Effortlessly convert milliwatts (mW) to decibel-milliwatts (dBm) with our convenient mW to dBm Conversion tool. Simply input the value in milliwatts, and our converter will provide you with the equivalent power in dBm. Whether for telecommunications, signal strength calculations, or RF engineering, our tool ensures accurate and quick conversions.
What is mW to dBm Conversion
To convert milliwatts (mW) to decibel-milliwatts (dBm), you can use the following formula:
dBm = 10 * log10(mW)
In this formula, log10 represents the base-10 logarithm.
For example, let's convert 2.5 milliwatts to dBm:
dBm = 10 * log10(2.5) dBm ≈ 3.979 dBm
Therefore, 2.5 milliwatts is approximately equal to 3.979 dBm.
How to convert mW to dBm
The power P(dBm) in dBm is equal to 10 times the base 10 logarithm of the power P(mW) in milliwatts (mW) divided by 1 milliwatt (mW):
P(dBm) = 10 ⋅ log10( P(mW) / 1mW)
So,
1mW = 0dBm
Example
Convert 20mW to dBm:,
P(dBm) = 10 ⋅ log10( 20mW / 1mW) = 13.0103dBm
