Concrete Volume Calculator
Calculate rectangular concrete volume from width, length, and thickness/height.
How to use
- Enter width and length in one common unit.
- Enter thickness/height in the same unit and calculate.
Capabilities and scope
A slab or prism is modeled as a simple rectangular solid.
How it works
It uses V=width×length×height.
Example
A 4m×5m×0.1m slab is 2m³.
Useful for
- Estimate theoretical slab or footing volume
- Compare concrete volume as dimensions change
Before you use it
- Placement loss, rebar displacement, uneven subgrade, and order allowance are not automatically added.
Frequently asked questions
Can I order exactly this amount?
It is theoretical geometry; actual orders should account for site allowance and supplier increments.
