Percentage Calculations
The Percent [%] key is used to find a per-
cent of a number or for working add-on,
discount or division percentages. It can be
used with any type of number, any
dimension (feet, inch, millimeter, etc.) and
convention (non-dimensioned, linear,
square or cubic).

500 [Feet] [x] 18 [%] 90 FT 0 IN
Add 10% for waste to 137 square feet:
137 [Sq] [Feet] [+] 10 [%] 150.7 SQ FT
Take 20% away from 552 feet 6 inches:
552 [Feet] 6 [Inch]
[–] 20 [%] 442 FT 0 IN
Divide 350 cubic yards by 80%:
350 [Cu] [Yds] [÷] 80 [%] 437.5 CU YD
