how much chlorine in pool

[dbl]

If I have a 10,000 gallon pool and my chlorine test kit indicates i have 4ppm - can you tell me how many gallons of chlorine I have in the pool.
thanks dbl

So we know that:
120,000 gallons of water = 1,000,000 pounds
1 ppm = 1 pound per 120,000 gallons of water

you need 4ppm for 10,000 gallons so:

10,000gallons/120,000=.08 pounds of water
.08 pounds of water x 4 (you need 4ppm) = so you have .33 gallons of chlorine in the pool.

I could be wrong but that is how I see the formula working out.
