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 %
Multiply ppm by 10000.
ppm=% X 10000 -DPS NOIDA
10 ppm = 10/1,000,000 = 1/100,000 = 1/100,000*100% = 0.001%
2/10 x 100 = 20%
10 ppm as a fraction is 10 / 1 000 000 = 0.00001, as a percentage = (10 / 1 000 000) * 100 = 0.001 %
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.
10 g is 10,000 mg and in 1 liter that would be 10,000 ppm. You need to have a volume in order to express the mass as ppm. In other words, 10 g NaCl cannot be expressed as parts per million unless you have the volume that it is in. If it's in a liter, then you will have 10,000 ppm.
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.
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.
10 ppm = 10/1,000,000 = 1/100,000 = 1/100,000*100% = 0.001%
to convert milligram per liter to percentage, multiply by 10000 Explanation one milligram per liter is 1 ppm 10000 ppm is 1 percentage
2/10 x 100 = 20%
