How to convert cubic feet to cubic yards
Divide the total cubic feet by 27. For example, 81 cubic feet ÷ 27 = 3 cubic yards. To reverse the calculation, multiply cubic yards by 27. You do not need a material density because both measurements describe volume.
This conversion works for any material or empty space. Material weight is a separate question that requires density.
When you need this conversion
Construction drawings may provide volumes in cubic feet, while landscape suppliers commonly sell bulk materials by the cubic yard. The conversion helps compare quotes on a consistent volume basis.
Reference examples
27 ft³ = 1 yd³; 54 ft³ = 2 yd³; 135 ft³ = 5 yd³; and 270 ft³ = 10 yd³. If you start with length, width and depth instead of a known volume, use the homepage calculator.
Frequently Asked Questions
Is a cubic yard larger than a cubic foot?
Yes. One cubic yard contains 27 cubic feet.
Does the conversion change for gravel or concrete?
No. Volume conversion is the same for every material; only weight-to-volume conversion depends on density.
