2–15 Unit Conversions
z
The calculators has a built-in unit conversion feature that enables
you to convert numbers from metric to English units and vice versa.
See Example 36.
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 [
T
] [
S
] to scroll through the list of units until a
appropriate units menu is shown, then [ ENTER ].
4. Pressing [
X
] or [
W
] can convert the number to another
unit.

To insert a constant at the cursor position ( See Example 37. ) :
1. Press [ CONST ] to display the physics constants menu.
2. Press [
X
] until the constant you want is underlined.
3. Press [ ENTER ].
3 Mode 1 - STAT
There are three menu operation in statistics menu :
1 -VAR
( for
analyzing data in a single dataset),
2 - VAR
( for analyzing paired
data from two datasets ) and
CLR- DATA
( for clearing all datasets).
See Example 38.
