I have some formulas i'd like to add within a calculator widget or page to my site. Some of this are "one rep max calc", "body mass index calc", "lean body mass calc". I understand there are a couple plugins that can do the "body mass index" calculation, but those are useless to me since my site is for bodybuilders and the calc use a couple more options, not only height, weight and sex.
How can i do this? Is there anyway i can convert an excel sheet into a calculator for wordpress or something like that, or any other way?
