Weight. The weight (tonnage) of a pile is determined by multiplying the volume by the density. CalRecycle's Solid Waste Cleanup Program has developed approximate pounds per cubic yard (lbs/cu yd) estimates for various materials. The actual density depends on the homogeneous nature (uniformity) of the pile in both void space and material type.

the 'tapped bulk density'. Bulk density of free-flowing powders or granular materials can be determined by filling a container of known volume, at which stage the material is weighed and the 'loose bulk density' can be estimated. The container is then tapped and refilled until the material stops settling, at which stage
