How to Convert Cubic Yards to Cubic Feet
Converting cubic yards to cubic feet is a single multiplication step. Multiply the number of cubic yards by 27 to get the equivalent volume in cubic feet.
ft³ = yd³ × 27
(or equivalently: ft³ = yd³ ÷ 0.037037)
(or equivalently: ft³ = yd³ ÷ 0.037037)
The Math Behind the Conversion
One yard equals exactly 3 feet. To find how many cubic feet are in a cubic yard, cube both sides of that relationship:
1 yd = 3 ft
(1 yd)³ = (3 ft)³
1 yd × 1 yd × 1 yd = 3 ft × 3 ft × 3 ft
1 yd³ = 27 ft³
(1 yd)³ = (3 ft)³
1 yd × 1 yd × 1 yd = 3 ft × 3 ft × 3 ft
1 yd³ = 27 ft³
Worked Example
To convert 3.5 cubic yards to cubic feet: multiply 3.5 by 27.
3.5 yd³ × 27 ft³/yd³ = 94.5 ft³
Memory tip: Multiplying by 27 is the same as multiplying by 3 three times. So 5 yd³ × 3 = 15, × 3 = 45, × 3 = 135 ft³. Handy for rough mental checks.

Frequently Asked Questions
How do you convert cubic yards to cubic feet?
Multiply the number of cubic yards by 27 to get cubic feet. The formula is ft³ = yd³ × 27. For example, 3 cubic yards times 27 equals 81 cubic feet.
How many cubic feet are in one cubic yard?
There are exactly 27 cubic feet in one cubic yard. Because one yard equals 3 feet, you cube that to get volume: 3 × 3 × 3 = 27. So 1 yd³ = 27 ft³ exactly.
What is 1.5 cubic yards in cubic feet?
1.5 cubic yards equals 40.5 cubic feet. Multiply 1.5 by 27 to get the result: 1.5 × 27 = 40.5 ft³.
How many cubic feet is a yard of concrete?
One yard of concrete means one cubic yard, which equals exactly 27 cubic feet. Concrete suppliers measure by the cubic yard, so knowing that 1 yd³ = 27 ft³ lets you verify quantities and plan pours accurately.
How many cubic feet in 10 cubic yards?
10 cubic yards equals 270 cubic feet. Multiply 10 by 27: 10 × 27 = 270 ft³.
Is there a quick way to estimate yd³ to ft³ mentally?
Yes. Multiply by 27 in steps: first multiply by 3 to get a third of the answer, then multiply by 3 again, then one more time. For example, 4 yd³: 4 × 3 = 12, × 3 = 36, × 3 = 108 ft³. This works because 3 × 3 × 3 = 27.
