Yes it is. You're looking for as little ammonia as possible, hopefully 0ppm. If it's over ~25ppm in a common freshwater tank, you should take measures to reduce the levels through water changes or chemical means.
Jupiter's atmosphere is composed of the following:Molecular hydrogen (H2) - 89.8% (+/- 2.0%)Helium (He) - 10.2% (+/- 2.0%)Methane (CH4) - 3000 ppm (+/- 1000 ppm)Ammonia (NH3) - 260 ppm (+/- 40 ppm)Hydrogen Deuteride (HD) - 28 ppm (+/-10 ppm)Ethane (C2H6) - 5.8 ppm (+/- 1.5ppm)Water (H2O) - 4 ppm (varies with pressure)Small amounts of aerosols, including ammonia ice, water ice, and ammonia hydrosulfide
In a marine REEF aquarium nitrates should be kept as close to 0 ppm as possible. In a fish only marine aquarium you should strive to keep your nitrates below 20 ppm.
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
PPM or parts per million

Ammonia comes from fish waste.
Print speed is measured in pages per minute (ppm).
A warning alarm is usually set at 25 ppm. The main alarm is usually set at 50 ppm.

check the pH balance for ammonia
The depletion of ozone layer is measured in PPM. Here PPM is called as Parts Per Million.
mgl is milligrams per liter. For example if you had a water sample with ammonia as 25 mgl then there would be 25 milligrams of ammonia for each liter of water. If, on the other hand, the water sample showed 45 ppm of ammonia then there would be 45 parts of some quantity per one million units of the same quantity. This could be 45 gallons of ammonia peer one million gallons of water or 45 ounces of ammonia per one million ounces of water or 45 teaspoons of ammonia for each one million teaspoons of water and so on.Answer:Although the numerical value of 1 mg/L amd 1 ppm are the same (1 mg/L= 1mg/1kg=1 mg/1,000,000 mg where 1kg is the weight of 1 liter of water at 4oC) the ppm vallue is usually eserved for gases in other gases as 1 ppm by volume is also equivalent 1 ppm by molar measure.
