1.1 Commonly used concentration units
environment.des.qld.gov.auHowever, units expressed as parts per a number (e.g. parts per million, ppm) may still be encountered. The conversion of parts per number data to concentration units can be confusing. For this reason, a range of ...

For example, one part per million can be imagined as one red marble mixed in with 999,999 blue marbles, one inch in sixteen miles, or a minute in the space of two years. One part per billion is the same as two croutons in a

The salt content of water affects the distribution of animals and plant species according to the amount of salinity they can tolerate. For this
Converting ppm to ppt and µS to mS
www.4oakton.comConverting ppm to ppt: ppm = parts per million ppt = parts per thousand 1 ppm = 0.001 ppt 1 ppt = 1000 ppm A meter that reads 0 to 10,000 ppm is the equivalent of a meter that reads from 0 to 10.00 ppt. A reading of 5000 ppm is equal to a reading of 5.00 ppt. To convert ppm readings to ppt, divide the ppm reading by 1000.
