Quick Summary & Key Answer

To convert cubic feet to tons, multiply cubic feet by the material density in pounds per cubic foot (lbs/ft³), then divide by 2,000. For example, 100 cubic feet of gravel (at 105 lbs/ft³) equals 10,500 lbs, or 5.25 US tons.

27 cubic feet = 1 cubic yard.
Water weighs 62.4 lbs per cubic foot.
Cured solid concrete weighs 145 lbs per cubic foot.
