Enter the volume of the pool and the desired chlorine level into the calculator to determine the amount of chlorine needed. This calculator can also evaluate any of the variables given the others are known.

## Pool Chlorine Formula

The following formula is used to calculate the amount of chlorine needed for a pool.

Ch = (V * C) / 10

Variables:

- Ch is the amount of chlorine needed in ounces V is the volume of the pool in gallons C is the desired chlorine level in parts per million (ppm)

To calculate the amount of chlorine needed, multiply the volume of the pool by the desired chlorine level. Then divide the result by 10. This will give you the amount of chlorine needed in ounces.

## What is a Pool Chlorine?

Pool chlorine is a chemical compound used to sanitize and disinfect swimming pools. It works by killing bacteria, viruses, and other microorganisms present in the water, preventing the spread of diseases and maintaining the water clean and safe for swimming. Pool chlorine comes in different forms such as tablets, liquid, granules, or gas, and its levels need to be regularly monitored and adjusted to ensure the water’s pH balance is maintained.

## How to Calculate Pool Chlorine?

The following steps outline how to calculate the amount of chlorine needed for a pool using the given formula:

- First, determine the volume of the pool in gallons (V).
- Next, determine the desired chlorine level in parts per million (C).
- Next, gather the formula from above = Ch = (V * C) / 10.
- Finally, calculate the amount of chlorine needed (Ch).
- After inserting the variables and calculating the result, check your answer with the calculator above.

**Example Problem:**

Use the following variables as an example problem to test your knowledge.

Volume of the pool (V) = 500 gallons

Desired chlorine level (C) = 2 ppm
