Formula: area in square feet × depth in feet ÷ 27. Overage covers compaction, spillage and uneven ground.

Ballpark, not gospel. This estimates volume and weight from the numbers you punch in — densities are typical values that change with moisture and compaction. Always confirm with your supplier before ordering or hauling.

Questions people actually ask

Straight answers, no fluff. Then run your own numbers above.

How do you calculate cubic yards?

Multiply length by width by depth in feet, then divide the total cubic feet by 27. If depth is in inches, divide the inches by 12 before using the formula.

What is the formula for cubic yards?

The formula is length × width × depth in feet divided by 27. The result is cubic yards.

How many cubic feet are in a cubic yard?

There are 27 cubic feet in 1 cubic yard. Multiply cubic yards by 27 to convert to cubic feet.

Is a yard the same as a cubic yard?

No. A yard is a length of 3 feet. A cubic yard is a volume: 3 feet long, 3 feet wide, and 3 feet deep, equal to 27 cubic feet.

Should I order extra material?

Yes, most projects should include about 10 percent extra. This covers compaction, uneven ground, spillage, and small measuring differences.
