You can convert a value between any two units within the same category (such as length).

Example: Using the Catalog, convert 12 meters to feet. The desired expression is 12•_m►_ft.

1.

Type 12 on the entry line.

2.

On the Utilities tab, click to show the unit conversions.

Handheld: Press k3.

3.

Click the Length category to expand the list of pre-defined length units.

Handheld: Scroll to the Length category, and press Enter.

4.

Scroll to meter.

Handheld: Scroll to _m (noting the meter hint in the Help window).

5.

Press Enter to paste _m to the entry line.

6.

Click the Conversion Operator (►) at the top of the Units list, and press Enter to paste it to the entry line.

7.

Select _ft from the Length category, and press Enter.

8.

Press Enter to evaluate the expression.

 

As with the pre-defined units, user-defined unit names must begin with an underscore symbol.

Example: Using the pre-defined units _ft and _min, define a unit named _fpm that lets you enter velocity values in feet per minute and convert velocity results to feet per minute.

Now you can use the new velocity unit _fpm.
