Two shapes – one method
For rectangular sections, volume is length × width × thickness. For cores and cylinders, the calculator uses diameter and depth/length. The volume is then multiplied by material density.
Metric or imperial
Choose mm, cm or m for metric input, or inches and feet for imperial input. Density is shown as kg/m³ or lb/ft³, and the result can be displayed in kg or lb.
Use the right density
The default 2,400 kg/m³ is a common planning value for normal concrete, but actual density varies with concrete type, reinforcement and composition. Use a project-specific value when known.
Planning aid – not a lifting plan
The weight estimate can help before lifting, transport or further division. Lifting equipment, attachment, center of gravity, capacity, reinforcement and site safety still need to be assessed for the actual job.
Concrete Cutter is available for Android and iPhone.
