Adjusting Length Totals

You can adjust measurement totals using the equation field. Measurements can be manipulated with the equation field using Excel-type formulas. For example, multiplying the Length by a set number [l]*2.6 will multiply the total length by 2.6, this may require you to edit the measurement unit of measure to area for example. The formula follows the PMDAS rule: Parentheses (brackets) first, followed by multiplication, division, addition, then subtraction. Detailed information and examples on using formulas are provided in the article "Using Formulas." Refer to the Industry Articles for specific examples in construction, electrical, landscaping, painting, plastering/insulation, plumbing, and roofing.
