The

**Wilks coefficient**allows you to compare the strength of one powerlifter to another based on their body weight and maximum weight lifted. The formula to calculate the Wilks coefficient is given by:**Wilks coefficient**= (max weight lifted) * 500 / (a + bx +cx² +dx³ +ex⁴ +fx⁵)

where

**x**is the lifter’s body weight.For men, the coefficients for this formula are:
a = -216.0475144, b = 16.2606339, c = -0.002388645, d = -0.00113732, e = 7.01863E-06, f = -1.291E-08.

For women, the coefficients for this formula are:
a = 594.31747775582, b = -27.23842536447, c = 0.82112226871, d = -0.00930733913, e = 4.731582E-05, f = -9.054E-08
