ppm stands for "parts per million" and it is the amount of one substance in another substance. You would test for it using a test kit appropriate for whatever chemical level you are trying to determine, such as a chlorine test kit or a calcium hardness test kit.
You cant...Coz its not a ratio...You can find number of moles, weight, and etc but not ppm bcoz ppm is termed from composition
One can find out about ppm conversion when one goes to the website of Online Conversion and visits the forum where people provide answers to commonly asked questions.
ppm
There are ppm's to chlorine, pH, alkalinity, water hardness, copper etc., etc, etc, etc. Rethink and ask in a different format.
Residential pools: 1.0 - 3.0 ppm; Commercial pools: 3.0 ppm - 5.0 ppm; Bromine levels: 4.0 - 6.0 ppm
Zn < O.6 ppm Fe < 4.5 ppm Mn < 2.0 ppm Cu < 0.2 ppm
Carbon dioxide levels are not decreasing in the atmosphere, in fact, they are increasing. In 1960 levels were 316 ppm. In 1970 levels were 325 ppm. In 1980 levels were 338 ppm. In 1990 levels were 353 ppm. In 2000 levels were 369 ppm. In 2010 levels were 388 ppm. Jan of 2012 levels were 393.09 ppm. As of today we are at 393.68 ppm at Manua Loa.
46 ppm is 0.0046%
0.5Mm = 50 PPM
0.110 ppm = 0.000011%
0.028 ppm
Multiply ppm by 10000.
