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.

0.110 ppm = 0.000011%
Ppm stands per parts per million. There are 1,000,000 micrograms in a gram. Therefore micrograms per gram is already ppm.
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%.
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
1 gram per tonne is 1 ppm. So 250 grams is 250 ppm. A tonne is a metric tonne, 2214 pounds

ppm
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!
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.
