This calculator is based on a Drain Rock (loose rock) density of 2,835 lbs per cubic yard. For Base Rock (compacted rock), multiply your totals by 1.4 for a density of 4,000 lbs per cubic foot. Check with our staff for all final quotes. Cubic Yard and Ton Calculator: Enter your width and length of the area you are working on and our calculator will give you an automatic conversion.
