There is a factor of 10,000 between ppm and percentage: ppm stands for parts per million, whereas percent means per hundred, and there is a factor of 10,000 between one hundred and one million. To go from ppm to percentage, divide my 10,000 and from percentage to ppm multiply by 10,000. Hope this helps.
Multiply ppm by 10000.
ppm=% X 10000 -DPS NOIDA
10 ppm = 10/1,000,000 =0.001/100 = 0.001%
10 ppm as a fraction is 10 / 1 000 000 = 0.00001, as a percentage = (10 / 1 000 000) * 100 = 0.001 %
ppm is parts per million and thus a concentration. It can not be calculated from molecular weight.
to convert milligram per liter to percentage, multiply by 10000 Explanation one milligram per liter is 1 ppm 10000 ppm is 1 percentage
A percentage is 'parts per hundred' and there are possibly 100 of them. ppm is parts per million. There are 10 000 hundreds in a million. So multiply your percentage by 10 000. i.e. 3% x 10 000 = 30 000 ppm. but check my math.
1 ppm is one part per million, or one millionth - percentage (which is latin for per hundred) wise, 1 ppm is .0001%
In chemistry, parts per million or ppm is defined as the number of part of a solute that is in one million parts of a solution. The formula to calculate ppm is to divide the mass of the solute in grams by the combined mass of the solvent and solute also in grams. This value is multiplied by 1,000,000 ppm.
That should be 0.037%. the easy way to calculate ppm to % is take the ppm (370) divided by 10,000. 370/10,000=0.037% That's because you're starting with 370 per million & you want to convert to 370 per 100 (per 100 = %) So: 370/1,000,000 = 370/(10,000 x 100) = 0.037/100 = 0.037%
From 10 000 BC till 1860, the pre-Industrial Age, the carbon dioxide in air was approximately 278 ppm (0.0278%). In 1900 it was 295 ppm. In 1960 it was 315 ppm. In 1980 it was 335 ppm. In 1990 it was 350 ppm. In 2000 it was 369 ppm. In 2010 it was 388 ppm. In 2011 it was 392 ppm. (March 2011)
0.1 percent = 1,000 ppm 1 percent is 10,000 ppm. 2 percent is 20,000 ppm 3 percent is 30,000 ppm 10 percent is 100,000 ppm etc. Take the percent, move the decimal point 4 places to the right, and you have the ppm. You take it from here.
