This tool calculates the amount of salt needed for your pool based on its size and current salt levels.

## Pool Salt Calculator

Use this calculator to determine how much salt to add to your pool to reach the desired salt level.

### How to Use

- Enter the volume of your pool in gallons.
- Enter the current salt level (in ppm).
- Enter the desired salt level (in ppm).
- Click “Calculate” to see how much salt you need to add (in kilograms).

### How It Calculates

The calculator uses the following formula to determine how much salt to add:

- Convert pool volume from gallons to liters (1 gallon = 3.78541 liters).
- Calculate the amount of salt needed to reach desired levels in milligrams based on pool volume and salt levels.
- Convert the necessary amount of salt from milligrams to kilograms (1 kg = 1,000,000 mg).

### Limitations

- Please ensure all input fields are filled out. The calculator will not work with incomplete data.
- This calculator assumes that the entire pool volume and salt levels are uniformly distributed, which may not always be the case in real-world scenarios.
