Operations with units

Once a quantity accompanied with units is entered into the stack, it can be

used in operations similar to plain numbers, except that quantities with units

cannot be used as arguments of functions (say, SQ or SIN). Thus, attempting

to calculate LN(10_m) will produce an error message: Error: Bad Argument

Type.

Here are some calculation examples using the ALG operating mode. Be

warned that, when multiplying or dividing quantities with units, you must

enclosed each quantity with its units between parentheses. Thus, to enter, for

example, the product 12.5m × 5.2_yd, type it to read (12.5_m)*(5.2_yd)

which shows as 65_(m⋅yd). To convert to units of the SI system, use function

UBASE:

Note: Recall that the ANS(1) variable is available through the keystroke

combination „î(associated with the ` key).
