1. What is the Wilks Formula?

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

2. How Does the Calculator Work?

The calculator uses the Wilks formula:

Where:

• \( total\_lbs \) — Total weight lifted in pounds
• \( 16 \) — Conversion factor from pounds to ounces
• \( coeff\_oz \) — Wilks coefficient (oz version)

Explanation: The formula converts the weight from pounds to ounces, then multiplies by the appropriate coefficient to normalize across weight classes.

3. Importance of Wilks Score

Details: The Wilks score allows fair comparison of lifters' performances regardless of body weight, making it essential for competitions with multiple weight classes.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: Why convert pounds to ounces?
A: Some versions of the Wilks formula use ounces for more precise calculations, especially when dealing with lighter weights.

Q2: Where do I find the Wilks coefficient?
A: Coefficients are weight-class specific and can be found in official powerlifting resources or calculators.

Q3: What's a good Wilks score?
A: Scores above 400 are considered excellent for men, while above 300 is excellent for women, though standards vary by federation.

Q4: Does this work for metric weights?
A: No, this specific calculator is for pounds to ounces. For kg calculations, use a different version of the formula.

Q5: How often are coefficients updated?
A: The Wilks formula was updated in 2020 (Wilks2.0), so ensure you're using current coefficients.
