Cubic Feet vs. Cubic Yards — Reference Table
1 cubic yard = 27 cubic feet
// Because 1 yard = 3 feet, and 3³ = 27
Cubic yards = Cubic feet ÷ 27
Cubic feet = Cubic yards × 27
// Because 1 yard = 3 feet, and 3³ = 27
Cubic yards = Cubic feet ÷ 27
Cubic feet = Cubic yards × 27
| Cubic Feet | Cubic Yards | Context |
|---|---|---|
| 0.60 cu ft | 0.022 cu yd | One 80 lb bag of concrete |
| 7.48 cu ft | 0.28 cu yd | One US liquid gallon × 7.48 |
| 27 cu ft | 1 cu yd | One cubic yard — key benchmark |
| ~45 cu ft | 1.67 cu yd | ~75 bags of 80 lb concrete |
| 81 cu ft | 3 cu yd | Smaller bulk material delivery minimum |
| 270 cu ft | 10 cu yd | Full ready-mix concrete truck load |
Frequently Asked Questions
How many cubic feet are in a cubic yard?
There are exactly 27 cubic feet in one cubic yard. This is because 1 yard = 3 feet, and volume scales cubically: 3 × 3 × 3 = 27. This is one of the most important conversion facts in construction — concrete, gravel, mulch, and topsoil are all sold by the cubic yard.
How do I convert cubic feet to cubic yards?
Divide cubic feet by 27. For example, a 10×10 concrete slab at 4 inches thick = 10 × 10 × (4/12) = 33.3 cubic feet ÷ 27 = 1.23 cubic yards. Always round up when ordering.
