milliwatts (mW)
mW stands for milliwatts, which is a unit of power equal to one thousandth of a watt. It is commonly used to measure small electrical power levels.
Decibel-milliwatts (dBm)
dBm stands for decibels relative to milliwatts, which is a unit of power measurement used in telecommunications and radio frequency engineering. It represents the power ratio in decibels (dB) referenced to one milliwatt.
How to convert mW to dBm
To convert milliwatts (mW) to dBm, you can use the following formula:
P(dBm) = 10 ⋅ log10( P(mW) / 1mW)
For Example – Convert 33 dbm to mw
Ans. P(dBm) = 10 ⋅ log10( 33mW / 1mW)
= 330 dBm

FAQs on mW to dBm conversion
How do you convert mW to dBm?
To convert mW to dBm, use the formula: dBm = 10 x log10(mW)
What is 1 mW the same as in dBm?
Using the formula: dBm = 10 * log10(1 mW) = 10 * log10(1) = 10 * 0 = 0 dBm
What is 200 mW in dBm?
Using the formula: dBm = 10 * log10(200 mW) ≈ 10 * log10(200) ≈ 10 * 2.3 ≈ 23 dBm
How is dBm calculated?
dBm is calculated by taking the logarithm (base 10) of the power level in milliwatts (mW) and then multiplying it by 10. dBm = 10 * log10(mW)
What is the value of 1 mW power?
The value of 1 mW power is 0 dBm.
