Understand the answer

The calculation, explained.

Loose volume = length × width × depth/12 in US units. Weight = volume × entered bulk density. US short tons divide pounds by 2,000; density is a product assumption.

How this tool works

Adjust the labeled inputs to see a new calculation. Units and assumptions are shown beside each field. Printed and copied results use the same calculation.

This is a planning estimate, not a structural design, permit document or binding quote. Check product specifications and actual site measurements.
