#HOW TO CALCULATE PPM FROM MOL HOW TO#
How to Convert Percent Concentration to PPM or Parts Per Million When converting percent concentrations of anything to parts per million remember that a 1 % (concentration) = 10,000 ppm or parts per million. Thanks to Leroy Jenkins for technical editing to clarify this point. To convert an 8 percent concentration of substance X to parts per million of X (in whatever, air, water, gas)Ĩ.0 % (concentration) x 10,000 = 80,000 ppm Example of conversion from percentage concentration of a substance to parts per million or ppm Notice where we place the decimal point if you want to stay out of trouble. To convert 800 ppm of gas X to percentage of gas X in air divide the ppm by 10,000 Example of conversion from parts per million to the percentage concentration of a substance Just watch the decimal point and we can avoid embarrassment. If I make a Carbon monoxide (CO) measurement and my instrument tells me I've got 800 ppm of CO, and my hygienist asks me to write the report in percent concentrations what now? People often talk about concentrations without stating the "in what" substance (Y) because they think we know what the heck they're talking about. We are calculating the percentage concentration of X in Y even if "Y" is not being stated. ( Parts per million (ppm) of X ) divided by ( 10,000 ) = Percentage concentration of X in Y Percent concentration of substance X within another substance Y = ppm concentration divided by 10,000 Suppose we are given a parts per million measurement (ppm of X in Y) and we want to convert that to a percent concentration of X in Y. How to convert ppm concentration to percent concentration ACCURACY of PPM or % CONCENTRATIONS of GASES in AIR.CONVERSION TABLE ppm to / from % CONCENTRATION.FORMULA for ppm CONVERT to % CONCENTRATION.CONVERT PPM to % CONCENTRATION and vice versa.How to Convert Between Percent of a Gas in Air & Parts Per Million (ppm) of a Gas in Air Article Contents We also provide an ARTICLE INDEX for this topic, or you can try the page top or bottom SEARCH BOX as a quick way to find information you need. This article describes the simple math used to convert between parts per million (PPM) and percentage, such as how we convert a measurement of 800 ppm of CO 2 in air (indicated on our colorimetric gas measurement tube shown at page top) and a percentage concentration of that same gas in air. We have no relationship with advertisers, products, or services discussed at this website.Ĭonvert ppm to percent or percent to ppm: That is, 1 micrometer per some unit can be expressed as a PPM of a meter since a micrometer is 1m/1,000,000.InspectAPedia tolerates no conflicts of interest. Its use in physics is tied to proportional values or phenomena. Parts-Per notation isn’t just used in use in chemistry, it’s also used in physics. For example, the number of lead atoms per gram of water is then multiplied by 1,000,000. It’s used to describe the number of dissolved pollutants in water. It’s used to both describe and explain the abundance of materials in a solution.Īnother common use is in environmental engineering. The most common use for parts-per notation is in chemistry. The others PPB, PPT, and even PPQ (parts per quadrillion) are also part of this notation, often referred to as parts-per notation.Īlthough these units are dimensionless, the notation itself is recognized as part of the SI system of units. PPM is one of a set of dimensionless units used to describe small numbers, as stated above. For instance, if your number is still low, switch to parts per billion and so on. PPM is used to bring a really small number into a more realistic number that you can visualize and analyze. This can be done using the calculator above, or it can be done using a standard calculator or hand calculation.įinally, you need to analyze the results. Second, multiply the number you got in step one by 1,000,000.
Most often this is a number of atoms in some unit of volume or solution.įor example, the number of carbon atoms per amount of soil. How to calculate PPMįirst, you must determine the number you wish you calculate the parts per million of. 00005 atoms of oxygen per cubic meter of air, that means that in 1 million cubic meters you have 50 atoms per million units.
It’s a faction per million units of some number or value.įor instance, if you have. PPM is short for parts per million, which is exactly as it sounds. The following formulas are used to calculate PPM and other values. BPS Calculator (Basis Points Calculator).
Enter any given number, or values, to calculate the following values ppm, ppb, ppt, permille, and percentage.
