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.

1ppb=1ug/L and 1ug=1e-6g so you take that and divide it by the molar mass of the substance you're trying to get the molarity for. Example--> Lithium FW=6.94g/mol so (1e-6g/L)/(6.94g/mol)=1.44e-7mol/L
1 ppm = 1x10-6 parts per parts
1 ppb = 1x10-9 parts per parts
1 ppt = 1x10-12 parts per parts
1 ppm = 1x103 ppb = 1x106 ppt
You can't - one is a concentration, the other a distance.

about 0.003 parts per billion in the earth's crust.
Uranium is not so plentiful; one day the reserves will be exhausted. Applications of uranium: - nuclear fuel for nuclear power reactors - explosive for nuclear weapons - material for armors and projectiles - catalyst - additive for glasses and ceramics (to obtain beautiful green colors) - toner in photography - mordant for textiles - shielding material (depleted uranium) - ballast - and other minor applications
ppbv is an abbreviation for "parts per billion by volume"
In carbonaceous meteorites: cca. 10 parts per billion (as weight) or cca. 1 part per billion (as atoms).
Parts per Million and Parts per Billion. Parts of a solute per Million parts of the Solvent.
Gas concentration is often expressed in parts per million.
In the crust, the element helium is at a concentration of 8 parts per billion.
Nickel is an element. Therefore, in any nickel item it is 1 billion parts per 1 billion or 1 million parts per million.

The concentration of gold in sea water is very low, around 0.0011 parts per billion. This equates to about 13 billionths of a gram of gold per liter of sea water.
