To enter these prefixes, simply type the prefix using the ~ keyboard. For
example, to enter 123 pm (1 picometer), use:
123‚Ý~„p~„m
Using UBASE to convert to the default unit (1 m) results in:
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).
