How Many Tons Are in a Cubic Yard of Gravel, Sand, Limestone & River Rock?

Master the cubic-yard-to-ton conversion factor for 16 aggregate materials, including why moisture content and stone gradation shift quarry scale weights.

On average, 1 cubic yard of standard construction gravel weighs 1.35 to 1.42 US short tons (2,700 to 2,835 pounds). Conversely, 1 ton of gravel equals approximately 0.70 to 0.74 cubic yards (about 19 to 20 cubic feet).

However, assuming a flat "1.4 tons per yard" across every landscaping material can cause major ordering discrepancies when working with lightweight volcanic lava rock (0.68 tons/yd³) or heavy road base (1.49 tons/yd³).
