Gravel and Stone Calculator
Estimate gravel, stone, sand, or soil volume for a rectangular area. Use your material density and price to calculate weight and cost.
Estimate a rectangular gravel or stone layer. Enter the material density from your supplier if you need weight; no density is assumed.
Gravel and stone estimate
Enter length, width, and depth to estimate volume. Add density, pricing when you have those details.
Volume = length × width × depth × (1 + allowance ÷ 100). Weight = volume × the density you supply. Cost = volume or weight in the selected pricing unit × unit price.
1 yd³ = 27 ft³. A metric tonne is 1,000 kg; a US short ton is 2,000 lb. These estimates exclude delivery, labor, taxes, and minimum-order fees. Bulk density varies with material, moisture, and compaction; confirm the supplier's measurement basis.
How to use Gravel and Stone Calculator
- Enter the area's length, width, and fill depth in metric or imperial units.
- Optionally enter a waste allowance, supplier density, and unit price.
- Calculate volume and any supported weight or cost estimates.
What is Gravel and Stone Calculator?
The same volume can have different weights depending on material type, grading, compaction, and moisture. This calculator separates geometry from density: dimensions determine volume, while your supplied density determines mass. Metric tonnes and US short tons are labeled separately to prevent ordering mistakes.
- Volume in cubic meters, feet, and yards
- Supplier-specified density instead of hidden material assumptions
- Kilograms, pounds, metric tonnes, and US short tons
- Optional waste allowance and unit-price estimate
A practical example
Length 5 m · Width 4 m · Depth 0.1 m Density 1,600 kg/m³ (illustrative input)
2 m³ 3,200 kg · 3.2 metric tonnes
Frequently asked questions
Why must I supply a density to get weight?
A material name alone does not determine its bulk density. Ask your supplier for a value matching the delivered material and its condition.
Are all tons the same?
No. A metric tonne is 1,000 kilograms; a US short ton is 2,000 pounds. This calculator identifies each explicitly.
Does the estimate include compaction?
There is no automatic compaction factor. Use dimensions, density, and an allowance that match your supplier's measurement basis.
