NOTE TO METRIC USERS
The factory-set Stored Values and

Pro are set in imperial values. You can easily change these values to the metric values you use in your work. These values will be stored, even after the unit has been powered off, until you do a
Clear All (

Below are the metric default values used in the examples in this guide, along with instructions on how to change them from the imperial default values. Calculation results shown in the guide have been rounded. Your calculator’s LCD display will give results with as many as six digits to the right of the decimal.
