Dilution Ratio Calculator
Use this helpful Ratio Calculator to determine your needs.
Our dilution ratio calculator helps you determine the exact amounts of solute and solvent needed to achieve your desired dilution ratio. With built-in volume conversion, you can perform calculations in any units you prefer. For more details on calculating dilution ratios and to see examples, check out the article and our dilution ratio chart.
Many of our products are concentrated and offer a suggested Dilution Ration depending on usage.
The dilution ratio is the proportion of Concentrate/(Solute) (the substance to be diluted) to Water/(Solvent) (depending on solute). For example, a 1:3 dilution ratio means adding 1 unit of Concentrate/(Solute) to 3 units of Water/(Solvent), resulting in a total of 4 units of solution.
Variables in Dilution Calculations
- Concentrate ratio: Always 1 in our calculator.
- Water ratio: Any number greater than 0.
- Final volume: Desired amount of diluted liquid.
- Concentrate volume: Amount of concentrate used.
- Water volume: Amount of water/(solvent) used.
Knowing any two of these variables allows you to use the dilution ratio calculator effectively. E.g. Final Volume (container size) & Dilution Ratio.
Dilution ratio calculator – a practical example
You now know all the calculations, so let’s use a practical example to show how the dilution ratio calculator works.
- Let’s assume you have a container with a volume of 1 liter. You want to mix the cleaner concentrate with water. According to the label, the ratio of water to concentrate should be equal to 3:1 (so 3 parts water, 1 part concentrate).
- Calculate the concentrate volume (solute volume).
solute volume = final volume / (solvent ratio + solute ratio)solute volume = 1 liter / (3 + 1)solute volume = 1 liter / 4solute volume = 0.25 liter - Now, we can calculate water volume (solvent volume).
solvent volume = solute volume × solvent ratiosolvent volume = 0.25 × 3solvent volume = 0.75 liter - That’s all! Now you know that if the desired dilution ratio is 1:3 and your container size is 1 liter, you need to use 0.25 liters of concentrate and 0.75 liters of water.
Dilution chart
You will find example values of how much solute you need if you know the dilution ratio and the final volume in the dilution chart below. Let’s say you need the final volume of 1 liter. How much concentration do you need to dilute?
Dilution ratio | Concentrate volume | |
|---|---|---|
1 liter (1,000 ml) | 5 liter (5,000 ml) | |
1:1 | 500 ml | 2,500 ml |
1:2 | 333 ml | 1,665 ml |
1:3 | 250 ml | 1,250 ml |
1:5 | 167 ml | 835 ml |
1:10 | 91 ml | 455 ml |
