How to convert ppb to ppm

ppm and ppb are defined as:

1ppm = 1/106 = 10-6

1ppb = 1/109 = 10-9


1ppm = 1000ppb

The number of parts-per million xppm is equal to the number of parts-per billion xppb divided by 1000:

xppm = xppb / 1000

Example: 7000ppb is equal to 7ppm:

xppm = 7000ppb / 1000 = 7ppm
