No.
ppm is a pure number - a ratio. g per kwh is a measure of mass per energy with dimensions: [L-2][T2]
Ppm stands per parts per million. There are 1,000,000 micrograms in a gram. Therefore micrograms per gram is already ppm.
400ppm
Multiply by 10,000: 0.5 x 10,000 = 5,000 ppm
Ppm is parts per million. This is more commonly, milligrams per litre. To convert this to micrograms per metre cubed, you multiply by 1,000,000. 32593.86*1000000 is 32,593,860,000 micrograms per metre cubed.
ppm means parts per million; percent basically means parts per hundred. Therefore, to convert from ppm to percent you should divide by 10,000.
to convert milligram per liter to percentage, multiply by 10000 Explanation one milligram per liter is 1 ppm 10000 ppm is 1 percentage
1 ppm = 1.33 µg/m3
0.5Mm = 50 PPM
Multiply ppm by 10000.
1000 ppm = 1 ppb I think equation to convert ppm to ppb is: 1 ppm = 1000 ppb, or 1 ppb = 1/1000 ppm * * * * * Wrong way around, I am afraid. 1000 parts per billion is 1 ppm. To convert ppb to ppm divide by 1000.
by "ppm" I assume you mean "parts per million". 30 percent means 30 per 100, and 1,000,000 (a million) divided by 100 is equal to 10,000. This is the ration between ppm and percent. 30x10,000 is equal to 300,000, so 30 percent is equal to 300,000 ppm
322 ppm = 0.0322%
