Common job conversions

Inches to decimal feet

Takeoffs are often easier in decimal feet. Divide the inches by 12, so 6" is 0.5 ft, 3" is 0.25 ft, and 8" is about 0.67 ft.

Square feet to squares

Divide by 100. A 2,400 sq ft roof is 24 squares. The roofing calculator works this out with your pitch and waste.

Cubic feet to cubic yards

Divide by 27. Concrete, mulch and gravel are usually ordered by the yard, so the concrete calculator and mulch and gravel calculator show both.

Questions

  • 27. A cubic yard is 3 feet by 3 feet by 3 feet.
  • 100.
  • US gallons. An imperial gallon is larger, at about 4.546 liters, so check which one a product uses if you work in Canada or the UK.
