1 mg/L = 1 ppm
Assumption: 1 cm3 of pure water = 1g =1000mg
1 litre water = 1000 ml = 1000 g = 1 000 000 μl or 1 000 000 mg
1 mg/1 litre = 1 mg/ 1 000 000 μl = 1mg/1 000 000 mg = 1 ppm
Note:
mg/L is most frequently used in measurements of material in water or other liquids. ppm is used as a measure of gases in other gases and is based on volume or mole ratios not weight or mass. As a clarification ppm is usually written as ppmv (parts per million volume)
Multiply ppm by 10000.
Divide ppm by 10,000:50,000 / 10,000 = 5 %
No. ppm is a ratio - a pure number - whereas a litre (not litter!) is a measure of volume, with dimensions [L3].
Divide by 10000. For example - something with a concentration of 120ppm is 0.0012%
ppm means parts per million; percent basically means parts per hundred. Therefore, to convert from ppm to percent you should divide by 10,000.
MGL is a liquid measurement, lead based paint is measured in ppm or mg cm3.
how do you convert percent transmittance to mg/l
0.5Mm = 50 PPM
Multiply ppm by 10000.
322 ppm = 0.0322%
ppm means 1/1,000,000; percent means 1/100. Therefore, every percent is equal to 10,000 ppm. To convert from ppm to percent, you divide by 10,000.ppm means 1/1,000,000; percent means 1/100. Therefore, every percent is equal to 10,000 ppm. To convert from ppm to percent, you divide by 10,000.ppm means 1/1,000,000; percent means 1/100. Therefore, every percent is equal to 10,000 ppm. To convert from ppm to percent, you divide by 10,000.ppm means 1/1,000,000; percent means 1/100. Therefore, every percent is equal to 10,000 ppm. To convert from ppm to percent, you divide by 10,000.
*1000
Divide ppm by 10,000:50,000 / 10,000 = 5 %
To convert 0.06% selenium to ppm, you need to multiply by 10,000. Therefore, 0.06% selenium is equivalent to 600 ppm. To convert 600 ppm to 90 ppm, you would need to dilute the solution by a factor of 6.67 (600 ppm / 90 ppm).
Divide by 1000.
Multiply by 10,000: 0.0025 x 10,000 = 25 ppm
To convert 0.5 percent to parts per million (ppm), you multiply by 10,000. So, 0.5 percent is equal to 5,000 ppm.
