How do I convert tons to cubic yards?

Answer 1

Gravel is approximately 2,750 lbs per cubic yard. Hope this helps!

Answer

Loose weight of Dry Gravel = 2,490 lb/cy =>

1 Metric Tons or tonnes= 2204.62262 Pounds

2,490 lb/cy / (2204.62262 Pounds/ 1 Metric ton) = 1.1294450022471419621014321262838 Tonnes/ cy=>

Density

1.13 Metric tons / cy = 1.13 Metric tonnes / 1 cubic yard

or Weight/Volume

Weight Volume

1.13 Metric tonnes of Dry Gravel = 1 cy of Dry Gravel

Then of course, the reverse: Volume/ Weight = Specific Volume

in such that you must ID material to quantify. Anyway, this is the conversion factor. GO FIU Construction Management! Added hualing complexities- Bank weight (in the bank) 2800 lb/cy, loose weight (excavated and loose in truck) given above, percent swell (12) increases volume/less dense, swell factor (.89= loose weight/ Bank weight).
