Concrete Weight Calculator
Concrete is incredibly heavy, and knowing the total weight of your pour is essential for structural engineering, ordering the right amount of material, and ensuring your sub-base can handle the load.
Total Weight
2.88 Tonnes
2880 kg
Volume Required
1.20 m³
Standard reinforced concrete weighs roughly 2.4 tonnes per cubic metre. Wet concrete can be slightly heavier.
Frequently Asked Questions
How much does 1m³ of concrete weigh?
A standard cubic metre of reinforced concrete weighs approximately 2,400kg (2.4 tonnes). Lightweight concrete may be closer to 1,800kg.
Why is knowing the weight important?
If you are pouring a slab on an upper floor or over a cellar, you must ensure the structure can support the several tonnes of weight being added.
Does wet concrete weigh more?
Yes, wet concrete is slightly denser and heavier than dry concrete. Once it cures and excess water evaporates, the weight stabilizes.
How do I order concrete?
Most suppliers sell concrete by the cubic metre (m³). Use the volume result from this calculator to determine how much to order, adding 5-10% for waste.
