Since crushed stone has a unit weight of around 2700 lbs/yd³, and 1 ton is equivalent to around 2205 lbs. we can say that a ton of crushed stone is about 0.82 yd³ in volume. We obtain that value by dividing the weight in pounds by the unit weight in pounds per cubic yard: 2205 lbs / 2700 lbs/ yd³ = 0.8166 yd³ ≈ 0.82 cubic yards.
