How gravel is calculated
Estimate gravel volume from area and compacted depth, with an editable material density to convert volume to mass. Aggregate density varies with grading, moisture, and compaction, so use supplier data for a reliable tonnage order. A 500 ft² driveway layer 4 inches deep is about 6.17 cubic yards before compaction allowance. The calculation validates each input and keeps its stated units explicit. Use an adjusted depth or allowance; actual compaction depends on material and equipment. This is an estimate for the stated assumptions; confirm measurements and any applicable professional or local standards before relying on it.
volume = area × depth; estimated mass = volume × bulk densityA 500 ft² driveway layer 4 inches deep is about 6.17 cubic yards before compaction allowance.
Assumptions & useful context
The result depends on the values you enter and the method described above. Displayed numbers may be rounded; calculations use the unrounded values. Check that this model matches your situation before relying on it.
Frequently asked questions
Does it account for compaction?
Use an adjusted depth or allowance; actual compaction depends on material and equipment.
Why can weight vary for the same volume?
Stone size distribution, void space, moisture, and source affect bulk density.
