Gravel Calculator
This gravel calculator estimates the amount of gravel required based on the area to be covered, gravel depth, wastage and bulk density. It can calculate gravel requirements for a total area, rectangular area or circular area.
How to Calculate Gravel Quantity
Gravel quantity is calculated from the coverage area and the required depth.
When wastage is included, the required quantity is adjusted by the selected wastage percentage.
The calculator displays the required gravel volume in cubic metres (m³) and cubic feet (ft³).
Gravel Weight Calculation
Gravel weight depends on its bulk density. The calculator estimates weight using the selected density.
Actual gravel weight can vary depending on the material, grading, moisture content and compaction.
Gravel Cost Calculation
The calculator can also estimate the total gravel cost when the cost option is enabled. Price can be entered per tonne, cubic metre or cubic foot.
Actual material cost may vary depending on gravel type, supplier, location, delivery charges and order quantity.
Frequently Asked Questions
How much gravel do I need?
The amount of gravel required depends on the area being covered and the selected gravel depth. Enter these values in the calculator to estimate the required quantity.
How deep should gravel be?
The required depth depends on the application, ground conditions and type of gravel being used.
How is gravel weight calculated?
Gravel weight is estimated by multiplying the required gravel volume by the selected bulk density.
Can I calculate gravel for a circular area?
Yes. Select Circle and enter the diameter. The calculator determines the circular area and then calculates the required gravel quantity.
Does the calculator include wastage?
Yes. You can enter a wastage percentage to include additional gravel in the calculated requirement.
