1. What is the Wilks Equation?

The Wilks formula is used in powerlifting to compare the relative strength of athletes across different weight classes. This version converts kilograms to ounces before applying the coefficient.

2. How Does the Calculator Work?

The calculator uses the Wilks equation:

Where:

• \( total\_kg \) — Total weight lifted in kilograms
• \( 35.274 \) — Conversion factor from kg to oz
• \( coeff\_oz \) — Wilks coefficient for ounces

Explanation: The equation first converts the weight from kilograms to ounces, then applies the specific Wilks coefficient for ounces.

3. Importance of Wilks Score

Details: The Wilks score allows fair comparison of strength between lifters of different body weights, making it essential for competitions and rankings.

4. Using the Calculator

Tips: Enter total weight lifted in kilograms and the appropriate Wilks coefficient for ounces. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Why convert kg to oz for Wilks calculation?
A: Some competitions use ounces as the standard unit, requiring this conversion for accurate scoring.

Q2: Where do I find the coefficient value?
A: Wilks coefficients are published in official powerlifting tables based on body weight and gender.

Q3: What's a good Wilks score?
A: Scores above 400 are considered excellent for men, while above 300 is excellent for women in competitive powerlifting.

Q4: Are there different Wilks formulas?
A: Yes, there are versions for kg and lb directly, but this one specifically handles the kg-to-oz conversion.

Q5: Is this used in all powerlifting federations?
A: Most federations use Wilks or similar formulas, though some may use updated versions like IPF points.
