ppt to ppm conversion

 

How to convert ppt to ppm

ppm and ppt are defined as:

1ppm = 1/10⁶ = 10^-6

1ppt = 1/10¹² = 10^-12

So

1ppm = 10⁶ppt

The number of parts-per million x_ppm is equal to the number of parts-per trillion x_ppt divided by 10⁶:

x_ppm = x_ppt / 10⁶

 

Example: 7000ppt is equal to 0.007000ppm:

x_ppt = 7000ppt / 10⁶ = 0.007ppm
