The Wilks Coefficient calculator computes the comparative weight lifted coefficient between weight lifters based on the weight of the lifter (x) and the gender of the lifter, all combined by the Wilks Coefficient formula.

INSTRUCTIONS: Choose units and enter the following:

• (x)  weigh of the person
• (g)  gender of the person

Wilks Coefficient (WC): The calculator the coefficient as a real number (decimal). 

The Math / Science

The formula for the Wilk's Coefficient is:

    ` WCAW = 500/ (a+bx+cx^2+dx^3+ex^4+fx^5) `

where:

• WC = Wilks Coefficient 
• x = body weight of the lifter
• a,b,c,d,e,f = f(gender)

For men:

a = −216.0475144
b = 16.2606339
c = −0.002388645
d = −0.00113732
e = 7.01863E−06
f = −1.291E−08

For women:

a = 594.31747775582
b = −27.23842536447
c = 0.82112226871
d = −0.00930733913
e = 4.731582E−05
f = −9.054E−08
