## How to convert ppb to ppm

ppm and ppb are defined as:

1ppm = 1/10^{6} = 10^{-6}

1ppb = 1/10^{9} = 10^{-9}

So

1ppm = 1000ppb

The number of parts-per million x_{ppm} is equal to the number of parts-per billion x_{ppb} divided by 1000:

*x*_{ppm} = *x*_{ppb} / 1000

Example: 7000ppb is equal to 7ppm:

*x*_{ppm} = 7000ppb / 1000 = 7ppm

#### PPB to PPM

PPM stands for parts of gas per million parts of air, and PPB is parts per billion. If that's not easy to imagine, try these examples:

#### Part per million (ppm):

1 second in just under 2 weeks.

1 litre of water in a swimming pool.

#### Part per billion (ppb):

1 second in 32 years.

1 ml of water in a swimming pool (that's about the size of a sugar cube).

#### How to convert ppb to ppm?

ppm and ppb are defined as:

1ppm = 1/10^{6} = 10^{-6}

1ppb = 1/10^{9} = 10^{-9}

So

1ppm = 1000ppb

The number of parts-per million xppm is equal to the number of parts-per billion x_{ppb} divided by 1000:

x_{ppm} = x_{ppb} / 1000

#### Example:

7000ppb is equal to 7ppm:

x_{ppm} = 7000_{ppb} / 1000 = 7_{ppm}
