General Gravel Calculator
Estimates gravel volume and mass from area, depth and bulk density.
How it works
Gravel volume and mass
Formula and assumptions
Volume in m³ = area in m² × depth in cm ÷ 100. Estimated mass = volume × bulk density. Compaction, moisture and the supplier’s actual density can change the amount ordered.
Example
Use the sample values, calculate, and change one input at a time.
Frequently asked questions
Are results exact? Results depend on the assumptions and inputs above.
Can I use this for professional decisions? Verify critical results independently.

Frequently asked questions
Why can the delivered weight differ?
Bulk density varies with material grading, moisture and compaction; confirm density with your supplier.
What should I check before relying on the result?
Confirm the input units and assumptions described above; independently verify safety-critical, medical, financial or professional decisions.
How deep should gravel be?
Recommended depth depends on the project, gravel size, base preparation and intended use. Follow project specifications rather than relying on a universal depth.
Can I convert cubic yards to tons exactly?
Not without the material’s bulk density. Different gravel types and moisture levels weigh different amounts per cubic yard.
