A pound is a measure of mass (or monetary value). A ppm is a measure of concentration. The two measure different things and, according to basic principles of dimensional analysis, conversion from one to the other is not valid.

ppm means mg per litre. mg/l means 100ug/dl. Therefore there are 10 x 10 micrograms per decilitre in ppm. In other words, 10ug/dl is 0.1 ppm.
No, one percent is one part per 100. 1 ppm is equal to one part per 1,000,000. In other words, 1 PPM is 10,000 times smaller than 1%.
Oh, dude, it's like converting microgram per gram to parts per million (ppm) is a piece of cake. All you gotta do is multiply micrograms per gram by 1000 to get parts per million because there are 1000 micrograms in a milligram. Easy peasy, lemon squeezy!
To convert from ammonia liquid pounds to gas ppm, you need to know the concentration of the gas in the air. This conversion requires additional information such as the volume of the space, temperature, and pressure to calculate the ppm concentration of the gas. It is not a direct conversion since ppm is a concentration measurement while pounds represent a mass measurement.
1 gram per tonne is 1 ppm. So 250 grams is 250 ppm. A tonne is a metric tonne, 2214 pounds
355 parts per million (ppm) is a unitless measurement used to represent concentration. It cannot be directly converted into an imperial weight unit like pounds or ounces.
This question is poorly phrased. ppm or parts per million is a measure of the concentration of one element of a solution or gas. Pounds per volume is a measure of density and depends on the materials. The two measure different things and therefore there's no general conversion. Many are the engineers that are trying to convert ppm in wastewater to actual pounds for reporting purposes. And pounds has more meaning to the average individual than ppm does. Generally speaking, one may take: (ppm) x (flow of water (gal/"time")) x (conversion factor) = pounds per "time" In this example, time = 1 month. Therefore, the ppm of a pollutant in water may be converted to pounds by following the following equation: (note: ppm = mg/l) (mg/l)(gal/mo)(3.7854Lit/gal)(1Lb/453.59g)(1g/1000mg)=Lb/mo The conversion factor = 8.3454E-06 or 0.0000083454 Above can be simplified as follows: Monthly Gallons of Chemical x Density of Same Chemical in "Pounds/Gallon" x (# of Parts/1,000,000) (Unitless) = ...Pounds per month If Unknown, Density = Specific Gravity x 8.345, i.e., Water Weight in Pounds per Gallon Above both methods assume that PPMV value is in relation to the total volume of solvent or chemical used and not necessarily the total volume of inlet or outlet air of a process equipment. For PPMv of the outlet or inlet air, the calculations will be different as provided in EPA's AP-42 Conversion Table along with the use of air fuel ratio in case of combustion process. Good luck!
100 ppm is worse than 50 ppm. The higher the ppm value, the more concentrated the substance is in the solution. In this case, a concentration of 100 ppm is twice as much as 50 ppm.

PPM describes the amount of a substance in a sample. For example: If you have one million pounds of goo that is 1 part per million (PPM) GOLD, you would have one pound of gold in the million total pounds of goo. PPM is typically used to define how much of a pollutant is in a sample of air. If the sample was determined to be 6 ppm hydrocarbon in a sample, that would mean that of the million moles of the sample of air (the weight of the atoms that make up the sample) there would be 6 moles of the hydrocarbon specified, which, depending on the complexity of the hydrocarbon, could end up being one atom of the hydrocarbon in the sample.

Zn < O.6 ppm Fe < 4.5 ppm Mn < 2.0 ppm Cu < 0.2 ppm
115 ppm is equivalent to 0.0115% in water.
0.110 ppm = 0.000011%
0.5Mm = 50 PPM
