Question on how to convert units of weight...?
Skeptical science says that the human CO2 emissions in 2008, from fossil fuel burning and cement production, was around 32 gigatoones of CO2. http://www.skepticalscience.com/human-co2-smaller-...
The CDIAC expresses this number in metric tons of carbon: 8749 million metric tons. http://cdiac.ornl.gov/ftp/ndp030/global.1751_2008....
How can I convert gigatoones of CO2 into metric tons of C? Skeptical science is (I think) including the weight of the whole molecule, including the oxygen atoms. I believe that I need to factor in the weight of O2, but don't remember how.
Do these figures match up reasonably well?

The mass of CO2 is 44 amu and C is 12/44 = .2727 of the total. If there are 8.749 GT of C there are
8.749*44/12 = 32.08 GT of CO2. The numbers agree.
