As you perform arithmetic with unit objects, the HP 48 keeps track of
the units for you. When different unit objects of the same category
are added (or subtracted) the result is automatically converted to the
units of the last unit object entered (the level 1 object).
Example:
Add up the following lengths and report tire answer in
centimeters: 41 mm, 19 in, 5 ft, and 12 cm
S t e p 1 :
Enter the unit objects onto the stack.
