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

Step 1: Enter the unit objects onto the stack.

Step 2: Add up the units. Because the level 1 object has cm as its

unit, each addition converts the total to centimeters.
