Formulas and Coefficients
Use of coefficients
At some USA Powerlifting contests, “formulas” or “coefficients” may be used to compare performances (for the purpose of placing/awards) across weight, sex, and/or age.
Coefficients based on bodyweight and sex are called Wilks coefficients/numbers
Coefficients based on age also exist
How the coefficients are used:
1. The appropriate coefficient is selected for each lifter
2. More than one coefficient could be used (e.g., age and bodyweight coefficients)
3. The lifters’ totals (powerlifting or single-lift) are determined based on the heaviest weight(s) lifted
4. The respective coefficients are multiplied by the respective totals
5. The resulting scores in a division are ranked ordered
6. The highest score earns first place, the second highest score earns second place, etc.
