How to convert square feet to cubic yards
Square feet measure area, and cubic yards measure volume, so you need a depth. Multiply the area by the depth in feet, then divide by 27. If your depth is in inches, divide it by 12 first.
Square Feet to Cubic Yards table
Use the table to check your answer or to find common values quickly. It uses the same math as the calculator above.
| Square feet | Cubic yards (2 in deep) | Cubic yards (4 in deep) | Cubic yards (6 in deep) |
|---|---|---|---|
| 100 square feet | 0.62 | 1.24 | 1.85 |
| 250 square feet | 1.54 | 3.09 | 4.63 |
| 500 square feet | 3.09 | 6.17 | 9.26 |
| 1,000 square feet | 6.17 | 12.35 | 18.52 |
| 2,000 square feet | 12.35 | 24.69 | 37.04 |
| 5,000 square feet | 30.86 | 61.73 | 92.59 |
Worked example
Suppose you have 500 square feet. Using the same factors as the calculator, that equals 3.086 cubic yards (2 in deep). Round up when you are ordering material, because a small shortage costs more than a small surplus.
Frequently asked questions
How do I convert square feet to cubic yards?
Square feet measure area, and cubic yards measure volume, so you need a depth. Multiply the area by the depth in feet, then divide by 27. If your depth is in inches, divide it by 12 first.
How many cubic yards are in 1 square feet?
1 square feet equals 0.01 cubic yards.
Is the conversion exact?
Volume to volume conversions are exact. Anything involving weight, bags, area, or loads relies on a material or size you choose, so those answers are estimates.
Should I round up?
Yes. When buying material, round up to the next quarter or half yard and add a small allowance.
