Decibel Calculator

- simple to use calculator that converts two power levels into the decibel ratio.

The calculation of a power ratio in decibels requires the use of logarithms.

Our simple to use decibel calculator provides the calculation on your computer, be it a desktop, laptop or mobile device.

Simply enter the values for the input and output levels into the decibel calculator, press calculate, and the calculated answer will be provided.
