1. What is the Wilks Formula?

The Wilks formula (or Wilks coefficient) is used in powerlifting to compare the relative strength of lifters across different weight classes. It allows for fair comparison between athletes of different body weights.

2. How Does the Calculator Work?

The calculator uses the Wilks formula:

Where:

• \( total\_kg \) — Total weight lifted in kilograms
• \( 2.20462 \) — Conversion factor from kg to lbs
• \( coeff\_lbs \) — Wilks coefficient (dimensionless)

Explanation: The formula converts the total weight from kg to pounds, then multiplies by the appropriate Wilks coefficient for the lifter's body weight and gender.

3. Importance of Wilks Score

Details: The Wilks score is crucial in powerlifting competitions to determine the best overall lifter regardless of weight class. It helps normalize performance across different body weights.

4. Using the Calculator

Tips: Enter your total lifted weight in kilograms and your Wilks coefficient. The coefficient depends on your body weight and gender (available in Wilks coefficient tables).

5. Frequently Asked Questions (FAQ)

Q1: Where can I find my Wilks coefficient?
A: Wilks coefficients are available in standardized tables based on your body weight and gender. Many powerlifting organizations publish these tables.

Q2: Why convert kg to lbs in the formula?
A: The original Wilks formula was developed using pounds, so the conversion ensures compatibility with the coefficient tables.

Q3: Is Wilks score used in all powerlifting federations?
A: While widely used, some federations use alternative formulas like IPF Points (formerly GL points) or Reshel's formula.

Q4: How accurate is the Wilks formula?
A: It's generally good for comparing lifters between 40-150kg body weight. Newer formulas may be more accurate for extreme body weights.

Q5: Can I use this for other strength sports?
A: While designed for powerlifting, it's sometimes used in other strength sports, though sport-specific formulas may be more appropriate.
