Crush & Gravel Calculator
Crush & Gravel Calculator
Measure an aggregate layer and estimate volume, mass and cost.
The same gravel volume can have different weights because grading and moisture affect bulk density.
Start with the layer area and thickness, then enter a density suited to the supplied aggregate. Compare the resulting volume and mass before applying a purchase rate.
How to use Crush & Gravel Calculator
- Choose shape and measurement unit. Enter length, width, diameter and layer thickness.
- Enter loose bulk density, ordering allowance and aggregate quote.
- Select Calculate estimate. Read the returned values alongside the assumptions below before copying, exporting or acting on the result.
Why choose this tool?
Separate volume and weight figures help when one supplier quotes by load and another quotes by mass.
Before you use the result
Loose bulk density varies with grading and moisture. Change it to match your supplier.
Questions about Crush & Gravel Calculator
Can I leave the starting density unchanged?
Use it only as an example. Ask the supplier for a suitable bulk density or check delivered material before relying on the weight estimate.
What should I check before using Crush & Gravel Calculator?
Check Shape, Measurement unit, Length and Width. Use the exact units shown beside the controls and replace any example values with your own inputs.
