ppm to ppb conversion

How to convert ppm to ppb

ppm and ppb are defined as:

1ppm = 1/10⁶ = 10^-6

1ppb = 1/10⁹ = 10^-9

So

1ppm = 1000ppb

The number of parts-per billion x_ppb is equal to the number of parts-per million x_ppm multiplied by 1000:

x_ppb = x_ppm ⋅ 1000

 

Example: 7ppm is equal to 7000ppb:

x_ppb = 7ppm ⋅ 1000 = 7000ppb

PPM to PPB

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).
