Frequently asked questions
How do I convert DBM to DBM?+
W = 10^(dBm/10) × 0.001. The result is rounded for display only.
Why are these conversions non-linear?+
Decibel scales use logarithmic ratios. Converting between dB and linear units requires exponentiation or logarithms, so standard factor-based conversion does not apply.
How many watts is 0 dBm?+
0 dBm equals 1 milliwatt, or 0.001 watts.
How many watts is 30 dBm?+
30 dBm equals 1 watt.
What is dBm used for?+
dBm is used to measure small power levels in radio, wireless, and audio systems.
