Antilog Calculator

This antilog calculator can calculate the inverse logarithmic value of any arbitrary base. Number having natural base (e) can also be calculated.


Logarithms, sometimes known as logs, are the inverse of exponentials. The logarithm of a number ‘x’ in the base ‘a’ is defined as the number ‘n’ such that ‘an = x’.

The logarithm of a number is the value that the base must be raised to in order to get that number, i.e. the exponent.

Anti-logarithm (antilog)

The inverse technique of obtaining the logarithm of a number is called as Antilog, which is also known as “Anti- Logarithms.” Consider the case where ‘x‘ is the base ‘b’ logarithm of an integer ‘y’, and ‘y’ is the antilog of ‘x’.

If logb y = x, then y = antilog x

Antilog Calculator Use

  • This calculator is easy to use and understand.
  • To begin, simply enter the base value and log value in the appropriate fields.
  • The calculator will then display the result as an antilog value.
  • Note that you can use any base value, even the natural antilog (e constant).

Formula to Calculate Antilog of Any Number

antilog formula

Any number’s antilog is simply the base multiplied by that number. As a result, antilog10(8.5) = 108.5 = 316227766. This applies to the case for any base. Below are some of the examples,

Antilog2(6) = 26 = 64.
Antiloge(8) = e8 = 2980.957987041727.
