Carbon Content Calculator

For the formula: CcHhClclNnNanaOoPpSs, enter the number of each atom below.


The calculation of the carbon content on this page is based on the following equation:

C% = 12.01*c / (12.01*c + 1.01*h + 35.45*cl + 14.01*n + 22.99*na + 16.00*o + 30.97*p + 32.06*s)*100 (%)

If the sample does not contain inorganic carbon (e.g., carbonate), this calculation gives the organic carbon content, which can be directly used in biodegradability test like OECD 301B.
