Dry Volume of Concrete Calculator
The 1.54 (concrete) / 1.33 (mortar) factor explained and applied.
Mixing collapses the air between loose particles and water fills the voids — 1 m³ of finished concrete consumes ~1.54 m³ of loose cement+sand+aggregate. Every estimation question starts here.

Frequently asked questions
What formula does the Dry Volume of Concrete Calculator use?+
It computes concrete: ×1.54; mortar: ×1.33, per Standard estimation texts (Dutta, Chakraborti). The formula is displayed under the result along with a worked example substituted with your own inputs.
What should I keep in mind when using this calculator?+
Mixing collapses the air between loose particles and water fills the voids — 1 m³ of finished concrete consumes ~1.54 m³ of loose cement+sand+aggregate. Every estimation question starts here.
Does it include wastage?+
Yes — standard wastage/bulking factors are built in and stated in the formula line, so the quantity is an orderable number, not a bare geometric volume.
Is the Dry Volume of Concrete Calculator free to use?+
Yes — completely free, no sign-up, no limits. It runs client-side in your browser, so inputs stay private and results are instant even on slow connections.
