Question from Robert, a parent: I need to know how many pounds of dirt is in a cubic yard |
Robert,
It depends on the type of dirt, the moisture contend and whether it is loose or packed. There are densities on the SImetric site in the UK. (Scroll down to Earth.) The densities are in kilograms per cubic meter but Google can convert for you. For example they give the density of "Earth, loam, dry, excavated" as 1249 kg/cu.m. so go to Google and type 1249 kilograms per cubic meter in pounds per cubic yard. Google will respond with (1 249 kilograms) per (cubic meter) = 2 105.25811 pounds per (cubic yard).
I hope this helps,
Penny
