Compare a powerlifting total relative to body weight with the classic Wilks formula. The result is explicitly labeled classic Wilks because major federations may now use newer scoring systems.

It scales a powerlifting total using a body-weight coefficient so totals from lifters of different body weights can be compared under that scoring system.
No. The IPF replaced Wilks and later adopted IPF GL Points, so this calculator is explicitly for the classic Wilks method.
The classic polynomial can behave poorly outside intended ranges; this implementation follows practical bounds used by OpenPowerlifting rather than silently extrapolating.
