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