Crush & Gravel Calculator

Measure an aggregate layer and estimate volume, mass and cost.

Open this tool

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

Why use this tool

Separate volume and weight figures help when one supplier quotes by load and another quotes by mass.

Before relying on the result

Loose bulk density varies with grading and moisture. Change it to match your supplier.

Tool limitations

Loose bulk density varies with grading and moisture. Change it to match your supplier.

Questions

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.
