ppm is an abbreviation of parts per million. ppm is a value that represents the part of a whole number in units of 1/1000000.

ppm is dimensionless quantity, a ratio of 2 quantities of the same unit. For example: mg/kg.

One ppm is equal to 1/1000000 of the whole:

1ppm = 1/1000000 = 0.000001 = 1×10^{-6}

One ppm is equal to 0.0001%:

1ppm = 0.0001%

ppmw is an abbreviation of parts per million weight, a subunit of ppm that is used for part of weights like milligrams per kilogram (mg/kg).

ppmv is an abbreviation of parts per million volume, a subunit of
ppm that is used for part of volumes like milliliters per cubic
meter (ml/m^{3}).

Other part-per notations are written here:

Name | Notation | Coefficient |
---|---|---|

Percent | % | 10^{-2} |

Per-mille | ‰ | 10^{-3} |

Parts per million | ppm | 10^{-6} |

Parts per billion | ppb | 10^{-9} |

Parts per trillion | ppt | 10^{-12} |

ppm is used to measure chemical concentration, usually in a solution of water.

Solute concentration of 1 ppm is solute concentration of 1/1000000 of the solution.

The concentration C_{ }in ppm is calculated
from the solute mass m_{solute }in milligrams and the
solution mass m_{solution }in milligrams .

*C*_{(ppm)} = 1000000 × *m _{solute}*
/ (

Usually the solute mass m_{solute }is much smaller than the solution mass m_{solution}.

*m _{solute}* ≪

Then the concentration C in ppm is equal to 1000000 times the solute mass *m _{solute }*
in milligrams (mg) divided by the solution mass

*C*_{(ppm)} = 1000000 × *m _{solute}*

The concentration C in ppm is also equal to the solute mass *m _{solute }* in milligrams (mg) divided by the solution mass

*C*_{(ppm)} = *m _{solute}*

When the solution is water, the volume of mass of one kilogram is approximately one liter.

The concentration C in ppm is also equal to the solute mass *m _{solute }*
in milligrams (mg) divided by the water solution volume

*C*_{(ppm)} = *m _{solute}*

The concentration of carbon dioxide (CO_{2}) in the
atmosphere is about 388ppm.

The frequency stability of an electronic oscillator component can be measured in ppm.

The maximal frequency variation Δ*f*, divided by the
frequency f is equal to the frequency stability

Δ*f*_{(Hz)} / *
f*_{(Hz)} = *FS*_{(ppm) }/ 1000000

Oscillator with frequency of 32MHz and accuracy of ±200ppm, has frequency accuracy of

Δ*f*_{(Hz)} = ±200ppm
× 32MHz
/ 1000000 = ±6.4kHz

So the oscillator produces clock signal within the range of 32MHz±6.4kHz.

The supplied frequency variation is caused from temperature change, aging, supply voltage and load changes.

Find how many ppb are in 6ppm:

*P*_{(ppb)} = 6ppm
× 1000 = 6000ppb
