ppm / ppb / percent CONVERTER


To convert between units just type the know value. It will converted automatically to the other units. This tool can be used for the following convertions:
    · Percent (%) to ppm
    · ppm to percent (%)
    · ppm to ppb
    · ppb to ppm
    · Percent to ppb
    · ppb to percent


PPM / PERCENT. Concentration converter

Enter the known value:

1ppm = 1000 ppb
1%     = 10000 ppm
1%     = 10000000 ppb


ppm (parts per million)

One part per million is one part of solute per one million parts of solvent. It is a dimensionless unit. The equivalency between ppm and % (percent) is as follows:

    1 ppm = 0,0001%
    10.000 ppm = 1%

As water density is 1 kg/m3 (This is the value normally considered although it varies slightly with temperature, you can calculate it with accuracy with our water density calculator), one ppm is equivalent to 1 milligram of something per liter of water (mg/l). In general it is equivalent to 1 mg/kg.

ppb (parts per billion)

One part per bilion is one part of solute per one billion parts of solvet.
    1000 ppb = 1ppm = 0.0001%
    1 ppb = 0.001ppm = 0.0000001%
