THE NUMBERS, EXPLAINED
How to use this calculator.
Volume ratios do not establish chemical nutrient balance. Choose suitable ingredients separately.
Start with your inputs
Enter target volume (l), blend ratio parts. Keep amounts in the units shown on each field. The example is a starting point, not a recommended value.
| Input | Example value |
|---|---|
| Target volume (L) | 100 |
| Blend ratio parts | 2,1,1 |
A worked example
With the example inputs above, component volumes (l) is 50, 25, 25. Change the inputs to explore your own scenario.
| Result | Example answer |
|---|---|
| Component volumes (L) | 50, 25, 25 |
How this is calculated
Component volumes (L)
For each blend part x in b: a × x/sum(b).
Symbols and units
- a
- Target volume (L)
- b
- Blend ratio parts
Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Calculation steps and notation
sum(list) adds all entries in the list.
Assumptions and limits
Volume ratios do not establish chemical nutrient balance. Choose suitable ingredients separately.
Calculations use the values you enter. Blank or invalid inputs show an error instead of silently substituting zero. Results are displayed to useful precision; calculations retain the underlying numeric precision.
Questions about this tool
What does the result tell me?
Component volumes (L). The result applies to the method and inputs described above. Check the units and assumptions before using it in a decision.
Why might another calculator differ?
Differences in units, rounding, timing or model definitions can produce different answers. Compare the input definitions and the method, rather than only the final number. For this tool: Volume ratios do not establish chemical nutrient balance. Choose suitable ingredients separately.
Are my inputs stored or sent to AI?
Calculations on this page happen in your browser. The separate AI question finder sends its submitted conversation to OpenAI; these calculator fields are not sent. Favourites and recent tool names are stored locally. A shared link contains the inputs you choose to include.
