Frequently asked questions
How do I convert DBM to DBM?+
Ratio = 10^(dB/20). 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.
