Enter the total parts water and the total part substance into the Liquid Dilution Ratio Calculator. The calculator will evaluate and display the Liquid Dilution Ratio.

## Liquid Dilution Ratio Formula

The following formula is used to calculate the Liquid Dilution Ratio.

LDR = PW / PS
• Where LDR is the Liquid Dilution Ratio (water:substance)
• PW is the total parts water
• PS is the total part substance

To calculate a dilution ratio, divide the total parts of water by the total parts of the solution or substance.

## How to Calculate Liquid Dilution Ratio?

The following example problems outline how to calculate Liquid Dilution Ratio.

Example Problem #1:

1. First, determine the total parts water.
• The total parts water is given as: 50.
2. Next, determine the total part substance.
• The total part substance is provided as: 4.
3. Finally, calculate the Liquid Dilution Ratio using the equation above:

LDR = PW / PS

The values given above are inserted into the equation below and the solution is calculated:

LDR = 50 / 4 = 12.5 (water:substance)

Example Problem #2:

For this problem, the variables required are provided below:

total parts water = 60

total part substance = 3
