Methodology
Transparent calculation
BuildMeter converts every input to a consistent internal unit, applies the selected allowance, and rounds products up to whole purchasable units.
Cylinder volume = π × radius² × height. Multiply by quantity, apply the allowance, then divide by bag yield and round up.

FAQ
Concrete Cylinder Calculator questions
Should the diameter be measured inside the form?+
Yes. Use the intended finished concrete diameter inside the cylindrical form.
Does this calculate hollow cylinders?+
No. It assumes each cylinder is completely filled with concrete.
Can this size a structural pier?+
No. Pier diameter, reinforcement and bearing capacity require project-specific engineering.
