Parts per million (PPM) is the US standard unit of measurement of something in water. It tells us the density of a given substance dissolved in water, like free chlorine or calcium hardness. 1 PPM means that substance is one-millionth of the total amount of water. For example, just 1.0 ppm of free chlorine can be enough to keep a pool safe and disinfected.”’
Parts per million? A million of what? Parts of what? PPM is the US standard unit of measurement in water chemistry. It tells us the density of a given substance dissolved in water. Examples include free chlorine, calcium hardness, and total alkalinity.

Ppm in water stands for parts per million, and is a way of measuring very small densities of substances. While it might seem like a tiny amount–it is!–ppm can still have a large impact. For example, 1.0 ppm of free chlorine may not be enough to keep a pool algae-free, but it will keep the pool water safe and disinfected.
Parts per million (PPM) can help you manage your pool’s water chemistry. One part per million is one-millionth of the total amount of water. It tells you how much of a substance exists in that particular volume of water. For instance, 1.0 ppm of Free Chlorine? Means if you took a sample of your pool water and analyzed it for free chlorine, 1.0 ppm would be present.
Parts per million or ppm is a dimensionless measure of the concentration of something dissolved in water. For example, 1 ppm means one part per million parts. 1 ppm of free chlorine in your pool would give the same amount of free chlorine as 6 drops (1/2 tsp.) of liquid bleach in 10 gallons of water. Although it may seem like a small amount, low concentrations of pool chemicals can effectively protect and sanitize your swimming pool
Ppm stands for parts per million, and it is a unit of density. It tells you how many parts of something there are in one million parts of total water. Example: if we add 1 ppm of salt to water, then each litre or quart of that water will have 1 gram of salt in it. ppm is useful because it’s extremely sensitive to small changes in water chemistry. The pH level of your swimming pool, for example, may change by 0.1 over the course of a single day!
If you’ve ever wondered what parts per million (PPM) means, it’s easier to think of than the words themselves suggest. Basically, PPM is a density calculation: telling you how many parts of a given substance are contained in one types of water. To put it simply, one PPM is equivalent to one drop of ink in an Olympic-sized swimming pool. PPM is also represented by other units like mg/L and mg/kg and at Crystal Blue we tend to use mg/L as our standard unit of measure.
