How to calculate 20 ppm of chlorine for using in 1 ton capacity of washing tank. So how much quantity of chlorine should be added in 1000 liters of water.

How much quantity of chlorine should be added in 1000 liters of water to get 20 ppm. I also need the formula for calculating it.

Edit by Mod: Posts merged. Poster is reminded to avoid double posting.

1 ppm is 0.001g/L (or 1g/mL)

20 ppm is therefore (0.001 x 20 =) 0.02g/L.

So, in 1000 L, you will have 20 g.

In short, if you are working with 1000 L, you can add the amount of grams equal to the ppm.

500 liters of cold water gives 220 ppm as per manufacture instruction,
