Dilution Ratio Calculator

The dilution ratio calculator is an essential tool for determining the exact mixture proportions between a concentrated solution and a diluent, typically water.

For example, in a 1:10 dilution ratio, you would combine 1 part concentrate with 9 parts water, resulting in a total of 10 parts. If you needed 1 liter of final solution, you would use 100ml of concentrate and 900ml of water.

Dilution Ratio Calculation Formula

The formula for dilution calculations is:

C₁V₁ = C₂V₂

Where:

• C₁ = Initial concentration
• V₁ = Initial volume
• C₂ = Final concentration
• V₂ = Final volume

You have a 20% concentrated solution and need to prepare 500ml of a 4% solution.

Using the formula:

• 20% × V₁ = 4% × 500ml
• V₁ = (4% × 500ml) ÷ 20%
• V₁ = 100ml of concentrate

You would use 100ml of the 20% solution and add 400ml of water to achieve the desired 4% concentration in a total volume of 500ml.

Dilution Ratio Examples

Industrial Cleaning Solution

• Starting with a concentrated degreaser
• Required ratio: 1:30
• Final volume needed: 3 liters
• Calculation: 3000ml ÷ 30 = 100ml concentrate
• Add 2900ml water to achieve final volume

Laboratory Sample Preparation

• Blood sample dilution
• Required ratio: 1:5
• Final volume needed: 500µl
• Calculation: 500µl ÷ 5 = 100µl blood sample
• Add 400µl buffer solution

Agricultural Fertilizer

• Concentrated liquid fertilizer
• Required ratio: 1:100
• Final volume needed: 20 liters
• Calculation: 20000ml ÷ 100 = 200ml fertilizer
• Add 19800ml water
