Formula
Concrete volume formula
Concrete orders should include site conditions, compaction, formwork, waste, and supplier guidance.
Volume = length x width x depth
A 5 m by 4 m slab at 0.1 m depth needs 2 cubic meters of concrete.
FAQ6 common questions for this calculator.
FAQs
What depth unit should I use?+
Enter depth in centimeters; the calculator converts it into meters for volume.
Should I order extra concrete?+
Most jobs include a small allowance for waste and uneven subgrade.
How does the Concrete Calculator calculate the result?+
For the Concrete Calculator, it uses the Concrete volume formula: Volume = length x width x depth. A 5 m by 4 m slab at 0.1 m depth needs 2 cubic meters of concrete.
What information do I need to use the Concrete Calculator?+
Enter the site measurements, material settings, unit system, and waste or allowance fields shown in the form. Recheck measurements before using the Concrete Calculator for ordering.
How accurate is the Concrete Calculator?+
Concrete Calculator is a material estimate based on the dimensions, unit system, and allowance values entered. It uses the Concrete volume formula, but cuts, openings, site conditions, pack sizes, and code requirements can change the final quantity.
What should I check before using the Concrete Calculator result?+
For the Concrete Calculator, check every measurement, unit system, waste allowance, openings, site conditions, and supplier pack size. Use the estimate as a planning quantity before ordering materials.
