Unhappy ppb to ppm

Is there a chart to convert ppb to ppm
How small is a ppm? a golf ball in a football stadium?

Default Re: ppb to ppm

1 ppm = 1000 ppb
1 ppb = 1/1000 ppm

ppb is a unit of proportion equal to 1 part per billion, and ppm is a unit of proportion equal to 1 part per million.

You can really compare it to things like football stadiums, as it depends the size of both things. For things like minerals in water, 1 ppb could be in a solution no bigger than a glass of water.

For converting between ppm and ppb the temperature and pressure will not matter. Because it is a unit of proportion and you are converting to the same type of unit of proportion. Normally temperature and pressure matter, just not in this case.

I think you will find that 1ppm = 1000ppb not the other way round

30 ppm * 1000 = 30000 ppb

So if 1 ppm = 1000 ppb then 0.10 ppm = 100 ppb...right?
