Use the specified mix ratio basis.
Why are weight parts and volume parts different inputs?
Use the matching calculator
Use this decision sequence
- Read whether the exact product ratio is specified by weight or volume.
- Use the same basis for the total batch quantity.
- Split the batch by the supplied component parts.
- Use densities only if the selected product instructions actually support converting between bases.
Keep the quantities distinct
| Quantity or assumption | How to use it |
|---|---|
| 2:1 by volume | Two thirds of the total volume is component A. |
| 2:1 by weight | Two thirds of the total mass is component A. |
| Switching basis | Needs component densities and a compatible instruction. |
Worked comparison
A supplied 2:1 volume ratio for a 6 L additive-volume batch gives 4 L of A and 2 L of B. A supplied 2:1 weight ratio for a 6 kg batch gives 4 kg and 2 kg. Those statements do not make liters and kilograms interchangeable.
Check before using the estimate
The calculator does not choose a recipe, alter a manufacturer’s ratio or establish mixed-product performance.
All dimensions, product properties, prices and specifications in this example are illustrative arithmetic inputs. Use the values from your measured plan, selected product data sheet and supplier quote. This guide does not choose construction specifications or certify safety.
