Aggregate Conversion Calculator

What is this calculator for?

Aggregate is sold in tonnes but often estimated in cubic metres — this calculator converts between both, plus cubic yards, for common granular materials. Use it when ordering base materials, comparing supplier quotes, or checking delivery quantities against plan quantities.

How to use it

• Select your material type — each has a preset density based on typical values
• Use Custom density if your supplier provides a specific bulk density
• Enter your quantity in any unit and get all conversions instantly
• Truck loads are calculated based on a standard 20 tonne payload
