About Logarithms

A logarithm is the inverse operation of exponentiation. For example, log base 10 of 100 is 2, because 10^2 = 100.

How This Calculator Works

Enter numbers separated by commas, select the desired base (10, e, or custom), and click "Calculate". The result will display the logarithms for each number.

Practical Uses

Logarithms are used in science, engineering, and computing for pH calculations, sound intensity (decibels), exponential growth, and data transformations.

Advice & Tips

Avoid negative or zero numbers, as logarithms are undefined for these. Use appropriate bases for your application.
