How it works
Weight = length × width × depth/12 × bulk density × (1 + compaction allowance).
Input definitions
- Area length (ft)
- Enter the value in the labeled unit.
- Area width (ft)
- Enter the value in the labeled unit.
- Compacted depth (in)
- Enter the value in the labeled unit.
- Bulk density (lb/ft³)
- Enter the value in the labeled unit.
- Extra for compaction (%)
- Enter the value in the labeled unit.
A worked example

Common questions
Why is area alone insufficient?
Gravel is ordered by volume or weight, so the compacted depth and material density are required.
How does Gravel volume and weight calculate the result?
Weight = length × width × depth/12 × bulk density × (1 + compaction allowance).
What should I verify before using Gravel volume and weight?
