I just got an email from somebody who noticed a slight discrepancy between his body fat calculations from my listed equations and from the enforcergraphics site.
My equation to convert Db to %BF was the 1963 Brozek equation. It is:
%BF = [(4.57/Db) - 4.142] * 100
Enforcergraphics uses the 1956 Siri equation. It is:
%BF = [(4.95/Db) - 4.5] * 100
You can use either equation, just make sure to ALWAYS use one or the other. Don't switch between the two.
Sorry for the confusion. Let me know if you guys have any questions.
