Creating Your Own User-Defined Units
In any category, you can expand the list of available units by defining a new unit in terms
of one or more pre-defined units. You can also use “standalone” units.

Why Use Your Own Units?
Some example reasons to create a unit are:
•
You want to enter length values in dekameters. Define
10_m
as a new unit named
_dm
.
•
Instead of entering
_m/_s
2
as an acceleration unit, you define that combination of
units as a single unit named
_ms2
.
•
You want to calculate how many times someone blinks. You can use
_blinks
as a
valid unit without defining it. This “standalone” unit is treated similar to a variable that
is not defined. For instance,
3_blinks
is treated the same as
3a
.
Note:
If you create a user-defined unit for an existing category, you can select it from the
UNITS dialog box menu. But you cannot use
3
to select the unit as a default for
displayed results.
