Concrete Weight Calculator
Enter length, width, and depth in metres to estimate concrete volume and weight using 2400 kg/m³.
Planning estimate only: plain normal-weight concrete uses 2400 kg/m³. Mix density varies; use a tested density and qualified engineering advice when needed.
A QUICK WALKTHROUGH
How to use this tool
- Enter length, width, and depth in metres.
- Calculate the volume and estimated weight.
- Use the result as a planning estimate.
Planning estimate
This calculator uses 2400 kg/m³ for plain normal-weight concrete. It is a planning estimate, not structural compliance advice or a substitute for a qualified engineer.
Mix density varies
Reinforced concrete is often around 2500 kg/m³, while lightweight concrete can be much lower. Use a tested mix density when available.
GOOD TO KNOW
Common questions
What density does it use?
It uses 2400 kg/m³, a typical estimate for plain normal-weight concrete.
Does it estimate reinforced concrete?
No. Reinforced concrete is often around 2500 kg/m³. Use a tested mix density for the material you will use.
Is the result exact?
No. This is a planning estimate. Concrete density varies by mix and aggregate, and it does not replace qualified engineering advice.
