Density varies by material: pea gravel runs about 1.3 tons per yard, standard crushed stone 1.4, and dense crushed granite up to 1.5. In metric, typical gravel is about 1.6–1.7 tonnes per cubic meter.
Suppliers sell by either unit, so this conversion is mostly for comparing quotes. When a quote is per ton, confirm whether the material is sold damp — moisture adds weight but not coverage.
