The Wilks calculator calculates your Wilks score based on your gender, bodyweight, and total weight lifted in the big 3 powerlifting exercises.
Also known as the Wilks Coefficient, the Wilks score was created for powerlifters to compare their strength regardless of their gender and weight.
Powerlifters on the lighter side usually have higher relative strength while heavier lifters have higher absolute strength.
So the Wilks score was formulated to create an even playing field between lifters in different weight classes.
