The calculator also provides reciprocal ( [ x

–1

] ), square root

( [ √ ] ), universal root ( [

] ), square ( [ x

] ) and

exponentiation ( [ ^ ] ) functions. See Example 47~50.

Unit Conversions

The calculator has a built-in unit conversion feature that enables
you to convert numbers from metric to English units and vice
versa. See Example 51.

1. Enter the number you want to convert.
2. Press [ 2nd ] [ CONV ] to display the menu. There are 7

menus, covering distance, area, temperature, capacity,
weight, energy, and pressure.

3. Use the [ ] [ ] to scroll through the list of units until a

appropriate units menu is shown, then [

4. Pressing

[ ] or [ ] can convert the number to another

unit.
