Measurement & Conversion Calculators

Convert between the units you measure in and the units suppliers sell in: feet, inches, square feet, square yards, cubic feet, cubic yards, and tons.

Quick answer: 1 yard = 3 feet; 1 square yard = 9 square feet; 1 cubic yard = 27 cubic feet. To convert cubic yards to tons, multiply by the material density, for example about 1.4 tons/yd³ for gravel or 1.2 tons/yd³ for topsoil.

The conversions behind every estimate

Most ordering errors come from mixing linear, square, and cubic units. A yard is 3 feet long, but a square yard is 3 × 3 = 9 square feet and a cubic yard is 3 × 3 × 3 = 27 cubic feet. Always convert inches to feet (÷ 12) before multiplying dimensions.

Volume to weight

Weight depends on the material: dry loose topsoil is roughly 1.0–1.3 tons per cubic yard, crushed stone about 1.4, sand about 1.35, and concrete about 2.0 tons. Wet material weighs more. Use the yards to tons calculator with your supplier's density when weight matters for a truck or trailer.

Frequently asked questions

How many cubic feet are in a cubic yard?

There are 27 cubic feet in one cubic yard, because a cubic yard measures 3 ft × 3 ft × 3 ft.

How do you convert square feet to square yards?

Divide square feet by 9. For example, 450 square feet ÷ 9 = 50 square yards.

How do I calculate square footage of a room?

Multiply length by width in feet. For an L-shaped room, split it into two rectangles and add them. A 12 ft × 14 ft room is 168 square feet.
