How do I convert cubic yards to tons? To roughly convert cubic yards to tons you can multiply your cubic yard figure by 1.4. Cubic yards × 1.4 = US tons (approx). This conversion will give an approximation for many sand and gravel products. To get a more accurate conversion, you'll need to involve a density figure in your calculation.
