ppm is an abbreviation for 'parts per million'.
Well, ppm usually means "parts per million". But I don't recall seeing this on any oscilloscopes. PPM could mean "Pulses Per Minute", which might make sense on an oscilloscope.
Assuming you mean a concentration of 0.023 as a mole fraction... 0.023 is equivalent to 23000 ppm
The mean concentration of mercury in the litosphere is 0,05 ppm.
The mean concentration of iodine in sea water is 0,064 ppm.
1 percent is 10,000 ppm .06 percent = (.06 x 10,000) = 600 ppm 90 ppm = (90 / 10,000) = 0.009 percent 0.06 percent is not the same thing as 90 ppm. This is not a math problem. You have to change the material. That's a chemistry problem.
ppm stands for parts per minute.
ppm means Parts per million
2 ppm means 2 parts per million.

Parts Per Million.

100 ppm is worse than 50 ppm. The higher the ppm value, the more concentrated the substance is in the solution. In this case, a concentration of 100 ppm is twice as much as 50 ppm.
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

Zn < O.6 ppm Fe < 4.5 ppm Mn < 2.0 ppm Cu < 0.2 ppm
115 ppm is 0.0115%.
0.110 ppm = 0.000011%
