Concrete Mix Calculator
Convert a target wet volume into ingredient volumes using a ratio and conversion factor you supply.
Your measurements
Example inputs; replace with your measurements.
Method, limits & sources
Dry volume = wet volume × supplied factor. Each ingredient volume = dry volume × its parts ÷ total parts.
Volumetric arithmetic only. The example ratio and conversion factor are not an approved mix design or a strength prediction. Use your specified mix and supplier guidance. Water quantity is not calculated.
Worked example & product data
At an illustrative factor of 1.54 and ratio 1:2:3, 1 m³ wet volume gives 0.2567 m³ cement, 0.5133 m³ sand and 0.77 m³ aggregate.
Independent geometry and quantity formulas; external references do not constitute professional review of this implementation.
