Converting Parts-Per-Million (ppm) to Parts-Per-Billion (ppb) is simple. Why is it simple? Because it only requires one basic operation: multiplication. The same is true for many types of unit conversion (there are some expections, such as temperature). To convert Parts-Per-Million (ppm) to Parts-Per-Billion (ppb), you just need to know that 1ppm is equal to ppb. With that knowledge, you can solve any other similar conversion problem by multiplying the number of Parts-Per-Million (ppm) by . For example, 10ppm multiplied by is equal to ppb.

1 ppm = ppb

5 ppm = ppb

10 ppm = ppb

15 ppm = ppb

25 ppm = ppb

100 ppm = ppb

1000 ppm = ppb

1 ppb = ppm

5 ppb = ppm

10 ppb = ppm

15 ppb = ppm

25 ppb = ppm

100 ppb = ppm

1000 ppb = ppm
