For example they give dense earth as 2002 kilograms per cubic meter. To convert this to cubic yards per ton type 2002 kilograms per cubic meter in tons per cubic yard into the Google search engine and Google will respond with (2002 kilograms) per (cubic meter) = 1.68724049 short tons per (cubic yard), so that's 1/1.68724049 = 0.5927 cubic yards per ton. I hope this helps,
