How to convert linear feet to cubic yards
For long, narrow jobs like curbs, footings, and drains, multiply the length by the width and the depth (all in feet), then divide by 27.
Linear 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.
| Linear feet | Cubic yards (2 in deep) | Cubic yards (4 in deep) | Cubic yards (6 in deep) |
|---|---|---|---|
| 50 linear feet | 0.93 | 1.85 | 2.78 |
| 100 linear feet | 1.85 | 3.7 | 5.56 |
| 200 linear feet | 3.7 | 7.41 | 11.11 |
| 500 linear feet | 9.26 | 18.52 | 27.78 |
| 1,000 linear feet | 18.52 | 37.04 | 55.56 |
Worked example
Suppose you have 200 linear feet. Using the same factors as the calculator, that equals 3.704 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 linear feet to cubic yards?
For long, narrow jobs like curbs, footings, and drains, multiply the length by the width and the depth (all in feet), then divide by 27.
How many cubic yards are in 1 linear feet?
1 linear feet equals 0.04 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.
