ORP to Chlorine Calculator

Formula

The formula to estimate the Chlorine Level (ppm) from ORP (mV) is:

$\text{Chlorine (ppm)} = \frac{\text{ORP} - 650}{200}$

Where:

ORP to chlorine conversion is the process of estimating the chlorine level in water based on its oxidation-reduction potential (ORP).

Example 1:

Using the formula:

$\text{Chlorine (ppm)} = \frac{750 - 650}{200} = 0.50 \text{ ppm}$

Example 2:

Using the formula:

$\text{Chlorine (ppm)} = \frac{900 - 650}{200} = 1.25 \text{ ppm}$
