PPT to PPM conversion


How to convert PPT to PPM:

1ppm = 1/106 = 10-6

1ppt = 1/1012 = 10-12

So

1ppm = 106ppt

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

xppm = xppt / 106


Example:

7000ppt is equal to 0.007ppm:

xppt = 7000ppt / 106 = 0.007ppm
