Concrete Weight Calculator
Estimate concrete weight from volume and density.
Calculation example
Inputs: Volume: 10 cu ft, Density: 150 lb/cu ft
Result: 1500 weight units
If 10 cubic units of concrete have a density of 150 weight units per cubic unit, the estimate is 1,500 weight units.
Formula
Estimated weight = volume × concrete density.
How to use this calculator
Multiply concrete volume by the density expressed in compatible units.
Before you calculate
Measure the project dimensions as accurately as practical and keep all measurements in compatible units. For material products, use the coverage, yield, density, or package size stated by the manufacturer or supplier rather than a generic assumption.
Choose the waste allowance based on the project shape, installation method, cutting requirements, and material characteristics. A simple rectangular estimate may need adjustment for openings, corners, slopes, joints, patterns, compaction, or other site conditions.
Understanding the result
The calculator provides a planning estimate based on the inputs shown above. It is not a substitute for project drawings, structural design, manufacturer instructions, or local requirements. Before ordering, compare the calculated quantity with the supplier's package sizes and ordering units.
Tips
- Use a density compatible with the volume units you entered.
