Excel Engineering Functions

The Excel Engineering Functions perform the most commonly used engineering calculations, many of which relate to Bessel Functions, Complex Numbers or converting between different bases. Engineers may also find the Excel Math and Trig functions useful.

In the tables below, the Excel Engineering functions have been grouped into categories, to help you to find the function you need. Selecting a function name will take you to a full description of the function with examples of use.

Note that some of the functions are new to Excel 2010 or Excel 2013 and so are not available in earlier versions of Excel.
