### A Table of the Common Logarithm

The table below lists the common logarithms (with base 10) for numbers between 1 and 10.

The logarithm is denoted in bold face. For instance, the first entry in the third column means that the common log of 2.00 is 0.3010300.

Note: This table is rather long and might take a few seconds to load! You can also download the table as an Excel spreadsheet. Printing in landscape mode on two pages should give satisfactory results.
