01 Measure the volume
Square feet × depth in inches ÷ 12 gives cubic feet. Divide by 27 for cubic yards. For irregular spaces,
add non-overlapping sections and enter their total as a known area. This is geometric volume with no
compaction or waste allowance.
02 Enter your material’s density
Estimated pounds = cubic feet × density in lb/cu ft. Divide by 2,000 for US short tons. Use supplier data
matching the product and moisture condition; this is not a measured delivery weight.
03 Compare bags and bulk
For weight-labeled bags, divide estimated pounds by pounds per bag. For volume-labeled bags, divide cubic
feet by cubic feet per bag. Round up once. Bulk rounds up to your supplier increment. The rounded order’s
weight is shown separately from the required weight.
