What this tool is for
Gravel Calculator is built for home project planning inside home calculators when you need to turns area and depth into gravel volume. It focuses on gravel instead of making you adapt a broad calculator to a narrow task.
When to use it
Use it when area and depth are already known and you want a fast estimate before comparing options, checking a worksheet, or copying the result into another workflow.
Inputs
- Area describes the size or distance used in the calculation. Use sq ft for this field.
- Depth describes the size or distance used in the calculation. Use in for this field.
Formula
cubic yards = area sq ft x depth inches / 324
Example
180 sq ft at 2 inches needs 1.11 cu yd.
