The units parts per billion, or ppb, works just like percent, except that instead of being out of 100, it is out of 1,000,000,000 (1 x 109)
For instance, if the concentration of a certain molecule is 5 ppb, that means for every billion molecules in the mixture, only five are that one molecule.
So to convert ppb to a percent, divide by 1 x 107.
You can also use parts per million (ppm), which is out of 1 x 106, or parts per trillion, ppt, which is out of 1 x 1012.
