How to convert cubic feet to cubic yards
Divide cubic feet by 27. A cubic yard is a cube 1 yard on each side. Each side is 3 feet, so the cube holds 3 × 3 × 3 = 27 cubic feet. Going the other way, multiply cubic yards by 27 to get cubic feet.
cubic yards = cubic feet ÷ 27
The international yard is defined as exactly 0.9144 m, which makes one cubic yard exactly 0.764554857984 m³ and one cubic foot 28.316846592 liters.[1] Those are the factors this converter uses.

Some rows are there because they match bags: 13.5 two-cubic-foot bags fill a cubic yard, as do 9 three-cubic-foot bags and 54 half-cubic-foot bags. The bags per cubic yard page has the full list.
From dimensions to cubic yards
Multiply length × width × depth in feet, then divide by 27.
If you have length, width and depth instead of a volume, convert every measurement to feet first. Depth is usually in inches, so divide it by 12.
cubic yards = length (ft) × width (ft) × (depth in ÷ 12) ÷ 27
A 10 × 10 ft bed filled 3 inches deep: 10 × 10 × 0.25 = 25 cu ft, and 25 ÷ 27 = 0.926 cubic yards. The cubic yard calculator does this for any shape and adds the weight and bag count.
Cubic meters and liters
One cubic yard is 0.765 m³, or 764.6 liters.
In the UK, Ireland, Australia and most of Europe, bulk material is sold by the cubic meter or by weight, and bags by liters. One cubic meter is 1,000 liters, 35.31 cu ft or 1.308 cubic yards. The cubic meter calculator works entirely in meters and centimeters.
Frequently asked questions
How many cubic feet are in a cubic yard?
27. A cubic yard is 3 ft × 3 ft × 3 ft.
How do I convert cubic feet to yards?
Divide by 27. For example, 54 cu ft ÷ 27 = 2 cubic yards.
How many cubic yards is 100 cubic feet?
100 ÷ 27 = 3.70 cubic yards.
How do I convert cubic feet to cubic yards for concrete?
The same way: divide by 27. A 10 × 10 ft slab 4 inches thick is 33.3 cu ft, or 1.23 cubic yards. Bagged mix is labeled by yield, such as 0.60 cu ft for an 80 lb bag; see how much a yard of concrete weighs for bags per yard.
How many liters are in a cubic foot?
28.3168 liters, from the exact definition of the foot (0.3048 m).[1]
