New version of MDCalc available

Via Over!My!Med!Body!: This tool is new to me, but I can imagine it might really be useful.

A wee bit about MDCalc
This site was created by a third-year medical student who got tired of having to wade through Google searches to find an easy to use, quick calculator for his medical equations. Many thanks to the multiple resources and references I’ve used to put this list together, including Medcalc, Pocket Medicine, 2nd Edition, eMedicine, and notes and teachings from my preclinical and clincal instructors.

Also worth noting, MCCalc produces results in either US and SI units.

Outside the US and use SI units? We’ve converted all our formulas to SI units and are looking for your help to validate them, so you can use them in the future!
