Salt Brine Calculator Online

Show Your Love:

The Salt Brine Calculator helps you determine the amount of salt needed to prepare a specific concentration of brine solution. This tool is useful for various purposes like de-icing roads, food preservation, and agricultural needs. By entering the desired concentration, the volume of the solution, and the density of water, you can quickly calculate the exact amount of salt required.

Formula of Salt Brine Calculator

The formula to calculate the amount of salt needed is:

Salt (in kilograms) = (Desired Concentration (percent) / 100) * Volume of Brine Solution (in liters) * Density of Water (in kilograms per liter)

Here is an example:

  1. Decide the desired concentration of the brine solution. For example, 23.3 percent.
  2. Measure the volume of the brine solution. For example, 100 liters.
  3. Use the density of water, which is 1 kilogram per liter.
  4. Plug these values into the formula:

Salt (in kilograms) = (23.3 / 100) * 100 * 1 = 23.3 kilograms

So, to make 100 liters of brine solution with a 23.3 percent concentration, you need 23.3 kilograms of salt.

General Terms and Conversion Table

To help users find the necessary information without calculating each time, here is a table for common brine concentrations and the required amount of salt for 100 liters of solution:

Example of Salt Brine Calculator

Let's go through another example to show how to use the Salt Brine Calculator.


  • Desired concentration: 10 percent
  • Volume of brine solution: 200 liters
  • Density of water: 1 kg/l

Using the formula:

Salt (in kilograms) = (10 / 100) * 200 * 1 = 20 kilograms

So, for 200 liters of brine solution with a 10 percent concentration, you need 20 kilograms of salt.

Most Common FAQs

How do I store brine solutions?

Brine solutions should be stored in clean, sealed containers to prevent contamination. Store them in a cool, dry place away from direct sunlight to maintain their effectiveness.

Can I use table salt for making brine solutions?

Yes, table salt can be used to make brine solutions. However, for large-scale applications like road de-icing, it is more economical to use bulk rock salt.
