Using UBASE (type the name) to convert to the default unit (1 m) results in:

Operations with units

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 (find it using the command catalog, ‚N):

NOTE: Recall that the ANS(1) variable is available through the keystroke combination „î(associated with the `key).

To calculate a division, say, 3250 mi / 50 h, enter it as (3250_mi)/(50_h) `

which transformed to SI units, with function UBASE, produces:
