Weight Calculator

How to use the Weight Calculator

1. Select the material type from the list — concrete, steel, timber, stone, etc.
2. Enter the volume or dimensions of the material.
3. Review the calculated weight in kilograms and tonnes.
4. Use the result for transport planning, crane hire, or structural checks.

Why use this tool

• Covers a wide range of construction materials with accurate density values.
• Essential for planning deliveries and ensuring the vehicle can carry the load.
• Useful for manual handling assessments where you need to know what a single unit weighs.

Knowing the weight of construction materials is critical for logistics, structural loading, and health and safety. A cubic metre of concrete weighs approximately 2,400kg — that is nearly two and a half tonnes. Natural stone varies from 2,200kg to 2,800kg per cubic metre depending on the type. Timber ranges from 350kg to 700kg per cubic metre depending on species and moisture content. This calculator stores standard density values for common materials and multiplies by the volume you enter. Use it when planning deliveries, specifying crane capacities, or completing manual handling risk assessments.
