Enter the decibel value into the calculator to determine the ratio. This calculator can also evaluate any of the variables given the others are known.

Db To Ratio Formula

The following formula is used to calculate the ratio from decibels (dB).

R = 10^{(dB/10)}


  • R is the ratio
  • dB is the decibel value

To calculate the ratio from decibels, divide the decibel value by 10 and then raise 10 to the power of the result. This will give you the ratio. This formula is based on the definition of the decibel, which is ten times the logarithm (base 10) of the ratio of two power quantities.

What is a Db To Ratio?

A dB (decibel) to ratio is a mathematical conversion used in various fields such as acoustics, electronics, and signal processing to express the ratio between two values in a logarithmic scale. It is commonly used to measure sound levels, signal strength, and power, among other things. The decibel scale allows for easier comparison and manipulation of these values, as it can represent very large or small numbers in a more manageable form.
