CONVERSION CALCULATOR
Conversion Calculator
In the construction aggregates industry, it is often necessary to convert between cubic yards and tons of a given resource. This can be a difficult process since cubic yards is a volumetric measurement while tons is a weight measurement. There is no definite standard for converting between cubic yards and tons. In fact, the conversion factor can vary greatly based on the type and density of material involved. The conversion factors for construction aggregate materials, both raw and recycled, can vary from ___ tons per cubic yard to ___ tons per cubic yard. If you know the density of the material in question, it is possible to calculate the conversion factor of tons to cubic yards. If you know the density in pound per cubic foot, multiply that density by 0.0135 (27/2000) to determine tons per cubic yard.
