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
PPM is an abbreviation for parts per million. If you have 1000ppm, then you have 1000 parts "A" per every million parts of your mixture. Therefore, the substance you are measuring is .1% part "A."
0.028 ppm
The mean concentration of iodine in sea water is 0,064 ppm.
ppm means Parts per million
ppm stands for parts per minute.
2 ppm means 2 parts per million.
If you mean ppm it is parts per million, i.e. mg per litre
To convert ppm mass basis to ppm volume basis: ppmm/molecular weight x 22.4 = ppmv

Parts Per Million.

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
The part per million (ppm) of a substance.
