Definition of Logarithmic Scale

A logarithmic scale is a non-linear scale that is used when your data has a large range of values.

The range of values between consecutive marks on the scale increases by a factor of \(b\), where \(b\) is the base of the logarithm.

\(10\) is the most commonly used base for logarithmic scales. The scale shown above is a base \(10\) logarithmic scale.

Logarithmic scales are used to record earthquake strength (the Richter scale is logarithmic), and sound intensity. Other uses include recording the intensity of light and the pH of solutions.
