One ton of gravel fills about 0.71 cubic yards. That is the same as saying a cubic yard of gravel weighs about 1.4 tons. Use the table to convert quickly.
How to convert
Divide the tons by 1.4 to get cubic yards of gravel. Ten tons divided by 1.4 is 7.14 cubic yards. Twenty tons is 14.3 cubic yards.
In cubic feet, one ton of gravel takes up about 19.3 cubic feet.
Why the number is not exact
Gravel weight depends on the stone, the size, and the moisture. Some suppliers use 1.35 tons per yard and others use 1.5. Ask the quarry what they use.
What about mulch?
The reverse is true for mulch. A ton of mulch is about 2.9 cubic yards, because mulch weighs only about 700 pounds per cubic yard. Never assume that a ton of one material equals a ton of another when you are thinking in yards.
Example: a gravel path
A path 3 feet wide and 60 feet long at 3 inches deep is 45 cubic feet, or 1.67 cubic yards. At 1.4 tons per yard that is 2.3 tons.
