Unit Conversions Calculators
Unit conversion calculators handle the everyday estimating conversions — square feet to acres, cubic feet to cubic yards, inches to feet, tons to cubic yards — so the numbers on your plan, your supplier's quote, and your tape measure all line up.
Frequently asked questions
Why do material estimates need so many conversions?
A plan might be in square feet, a supplier quotes gravel by the ton, the truck measures by the cubic yard, and your tape reads inches. Converting cleanly between them is half the work of any material takeoff.
How do I convert square feet to cubic yards?
You can't directly — area has no thickness. You need a depth. The Square Feet to Cubic Yards Calculator asks for both your area and your depth, then returns the cubic yards, which is what you actually order.
How many cubic feet are in a cubic yard?
27. A cubic yard is 3 feet on every side, and 3 × 3 × 3 = 27 cubic feet. That one number underlies most material conversions on a job site.
