This logarithm reference table shows the logarithm (log_base of number) for a range of number values, assuming a base of 10. Every figure is computed with the same engine that powers our Logarithm Calculator, so the numbers are exact.

How to use this table
Find the row closest to your number and read across to the logarithm (log_base of number). For a value between two rows, the real figure sits between them — or enter your exact numbers in the Logarithm Calculator for a precise answer.
Need a value that is not in the table? — the Logarithm Calculator does it instantly, for free, with the formula and a worked example built in.
