Most prefixes used by the HP 48 correspond with standard SI
notation, with one exception: “deka” is “D” in HP 48 notation and
“da” in SI notation.
Note
You cannot use a prefix with a built-in unit if the
resulting unit matches another built-in unit. For
example, you cannot use min to indicate milli-inches,
because min is a built-in unit indicating “minutes,”
Other combinations that match built-in units are
F'-=i,
Converting Units
The HP 48 provides several w^ays to convert unit objects to different
units;
■ The UNITS Catalog menu—converts to built-in units only.
■ The CONVERT command—converts to any units.
■ The UBASE (base units) command—converts to SI base units only.
If you’re working with temperature units, see “Working with
Temperature Units” on page 10-10.
