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
To calculate water hardness in parts per million (ppm), you can use the formula: Hardness in ppm (Hardness in mg/L) x 1.0.
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 %
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%
To convert parts per million (ppm) to a percentage, divide the ppm value by 10,000. For example, if you have 500 ppm, you would divide 500 by 10,000 to get 0.05. Then, multiply by 100 to get the percentage, which would be 5%.
Percent = per 100,ppm = parts per million = per 1,000,000So 24 / 100 = 240,000 / 1,000,000 (count number of non-bolded italiczero's!)24% = 240,000 ppm
No, a 100 ppm NaCl solution means there are 100 parts per million of NaCl (sodium chloride) in the solution, not just sodium (Na) alone. To calculate the amount of sodium ions (Na+) in the solution, you would need to consider the molar mass of NaCl and the percentage of Na+ in NaCl.
.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)
In 1965, the percentage of carbon dioxide in the Earth's atmosphere was around 320 parts per million (ppm), which is equivalent to about 0.032%. This is much lower compared to current levels, which have risen to over 400 ppm.
