ppm to ppt conversion How to convert ppm to ppt. ppm and ppt are defined as: 1ppm = 1/10 6 = 10-6. 1ppt = 1/10 12 = 10-12. So. 1ppm = 10 6 ppt. The number of parts-per trillion x ppt is equal to the number of parts-per million x ppm multiplied by 10 6:

ppm to ppt conversion How to convert ppm to ppt. ppm and ppt are defined as: 1ppm = 1/10 6 = 10-6. 1ppt = 1/10 12 = 10-12. So. 1ppm = 10 6 ppt. The number of parts-per trillion x ppt is equal to the number of parts-per million x ppm multiplied by 10 6:. x ppt = x ppm ⋅ 10 6. Example: 7ppm is equal to 7000ppb:
