2021-02-23 ppm to ppb conversion How to convert ppm to ppb. ppm and ppb are defined as: 1ppm = 1/10 6 = 10-6. 1ppb = 1/10 9 = 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: Parley's PPM Plumbing, Heating & Air Conditioning, Orem, UT. 1,049 likes · 71 talking about this · 1 was here.
