Example Data Table
| Scenario | Known Inputs | Calculated Output | Use Case |
|---|---|---|---|
| Ratio to volume | 1:9 ratio, 20 L batch | 2 L concentrate, 18 L water | Routine cleaning blend preparation |
| Actual ratio | 300 mL concentrate, 1200 mL water | 1:4 normalized ratio | Check a prepared mixture |
| Target concentration | 25% stock, 5% target, 1000 mL final | 200 mL stock, 800 mL water | Dilution from strong stock solution |
Formula Used
1) Ratio to total volume: Concentrate volume = (concentrate parts / total parts) × target volume. Water volume = (water parts / total parts) × target volume.
2) Actual ratio from measured liquids: Water-to-concentrate ratio = water volume / concentrate volume. Concentrate percentage = (concentrate volume / total blend volume) × 100.
3) Dilution from stock concentration: C1V1 = C2V2. Stock volume = (target concentration × final volume) / stock concentration. Water volume = final volume - stock volume.
These relationships assume complete mixing, stable temperature, and compatible concentration units.

Frequently Asked Questions
What does a 1:9 mixing ratio mean?
It means one part concentrate is combined with nine parts water. The final mixture contains ten total parts, so concentrate makes up 10% of the blend.
Can I use liters, milliliters, or gallons?
Yes. The calculator accepts several volume units. Keep all entered values within the same selected unit for each calculation mode.
Why is the target concentration lower than stock concentration?
When you dilute with water, the stock solution must start stronger than the final target. Otherwise, dilution alone cannot reach the requested concentration.
What is dilution factor?
Dilution factor shows how many times the stock has been weakened. A factor of 5 means one volume of stock becomes five volumes after adding water.
Should I include waste or overfill allowance?
Yes, if you expect transfer loss, dead volume, or sampling loss. The ratio-to-volume mode includes an extra allowance percentage for this purpose.
Does temperature affect mixing calculations?
Volume can shift slightly with temperature. For routine work, the difference is often small, but critical laboratory preparation may require temperature-controlled measurements.
Can this calculator replace a formal lab procedure?
No. It is a planning and verification aid. Follow your lab method, safety documentation, and material compatibility guidance for real chemical preparation.
