How gravel volume is calculated
Multiply length, width and depth to get cubic feet, then divide by 27 for cubic yards.
cubic yards = length × width × depth(ft) ÷ 27
Weight is approximate because density changes with rock type, grading and moisture.

Why can actual tonnage differ?

Should I compact the gravel?
Compaction requirements depend on the material and project.
