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.

What is the percentage of 10 ppm?

10 ppm as a fraction is 10 / 1 000 000 = 0.00001, as a percentage = (10 / 1 000 000) * 100 = 0.001 %

How convert percentage to ppm?

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.

How do you calculate parts per million?

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.

What is the definition of PPM as it relates to a chemical shift?

The term PPM stands for "parts per million." Chemists use this notation to describe the concentrations of things that are diluted. To make it a percentage, 1 PPM is equal to 0.0001%.

How does a person know what ppm of carbon dioxide exists if the hand pump detector tubes are scaled by volume percentage?

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.

The concentration of carbon dioxide CO2 in air is 380 ppm What is this in a percentage using significant figures?

.000380 is 380 millionths, ppm is to millionths what % is to hundredths. If you now move the decimal two places to the right to conver to a percentage, then 380 ppm is approximately .04%, and thus, CO2 makes up .04% of the air (which is what I assume this question is refering to)

Convert 370 ppm carbon dioxide to a percentage?

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%
