Mixing Ratio Calculator
Either compute component volumes from a target ratio or determine the ratio from measured volumes.
Component A volume
200 mL
Component B volume
800 mL
How to Use This Calculator
Select your workflow
Choose whether you want to compute required volumes from a ratio or determine the ratio based on measured volumes.
Enter known values
Provide part counts or component volumes depending on the selected mode.
Review the output
The calculator returns precise component amounts or a simplified ratio for mixing instructions.
Scale to any batch size
Ratios and volumes scale linearly, so update inputs for larger or smaller batches as needed.
Formula
Volume = (parts / Σparts) × batch volume
Ratio = Volumeₐ / Volume_b
Part-based mixing ensures components keep their relative proportions regardless of total batch size.
Example
A 1:4 fertilizer mix scaled to 10 gallons requires 2 gallons component A and 8 gallons component B.
Full Description
Mixing ratios are common in coatings, adhesives, fertilizers, and chemical preparations. They simplify instructions by specifying how many parts of each component to combine rather than exact amounts.
This calculator translates between parts and actual volumes, making it easy to scale recipes while maintaining the correct proportions. It also works in reverse, converting measured volumes back into a ratio for documentation or quality control.
Frequently Asked Questions
Can I use mass instead of volume?
Yes, if the components are measured by mass. Replace volume units with grams or kilograms. Ratios are unitless.
How do I handle more than two components?
Extend the concept by adding more parts. For now, compute pairwise or adapt calculations manually for additional components.
Does temperature or density matter?
If densities differ significantly, consider measuring by mass for greater accuracy. The calculator assumes equal units across components.
Can I simplify the ratio?
Divide both parts by their greatest common divisor to obtain a simplified whole-number ratio for instructions.
What about precision?
Use sufficiently precise measuring tools. Small errors in ratio can lead to noticeable differences in product performance.
