CALCULATION GUIDE

Know what is included.

Enter measurements from your drawings or site records. This worksheet uses the dimensions you provide.

Concrete slab
Area = length × width. Volume = area × thickness.
Wall or rectangular surface
Gross area = length × height (wall) or length × width (surface). Net area = gross area − opening areas.
Pipe and fittings
Pipe lengths are added together. Fittings are counted separately.
Mixed units
All dimensions are converted to the chosen result unit before quantities are calculated. 1 ft = 0.3048 m. 1 in = 0.0254 m.
Repeated items
Copies multiply every quantity on the line, including the same openings.
Opening positions
Opening width follows the parent's length. Height follows its height or width. x and y locate the bottom-left corner in the opening unit. Positioned openings are checked for overlap and must have one copy. Without positions, deductions are treated as separate and non-overlapping. Check the layout on your drawing.

No waste, reinforcement, costs, structural design or ordering allowances are included. A rectangular sketch is a reference, not a scaled drawing.
