How is gravel volume calculated?

Gravel volume is calculated by multiplying the Length, Width, and Depth of the area you want to cover. The basic formula is Volume = Length × Width × Depth. Our calculator handles unit conversions to ensure all measurements are consistent before calculating.

How do I convert cubic feet to tons or cubic meters?

To convert volume to weight (like cubic feet to tons), you need the gravel's density. The formula is Weight = Volume × Density. A common density for gravel is about 1.6 tons per cubic yard. To convert between volume units, you can use standard conversions: 1 cubic yard = 27 cubic feet, and 1 cubic meter ≈ 35.31 cubic feet.

What density values should I use for gravel?

Gravel density varies by type. Common compacted gravel is around 1.6 tons per cubic yard (2,560 kg/m³ or 100 lbs/ft³). Pea gravel is lighter, around 1.5 tons per cubic yard. For accurate results, it's best to ask your gravel supplier for the specific density of the material you're purchasing.

Can I estimate gravel for sloped surfaces?

Yes. For sloped or uneven surfaces, it's recommended to add an extra percentage to your total volume to account for inconsistencies and ensure full coverage. Our calculator includes an 'Extra Allowance' field where you can add 5-15% to compensate for slopes, compaction, and potential measurement errors.

Is this calculation accurate for large construction projects?

This calculator provides a highly reliable estimate for planning and budgeting purposes. However, for large-scale, critical construction projects, we strongly recommend consulting with a civil engineer or construction professional. They can account for specific site conditions, soil compaction, and local material specifications that may affect the required volume.
