# Powerlifting Coefficient (DOTS / IPF GL) Calculator

Compare a powerlifting total across four strength coefficient systems side by side: DOTS, Wilks (1994), IPF GL Points and Goodlift. Enter sex, body weight and three-lift total (squat + bench + deadlift) in kg or lb, and see each formula's points, coefficient, relative-strength tier and a progress bar showing how close the total is to each system's elite threshold. Complements the existing Wilks calculator by adding DOTS and IPF GL rather than replacing it.

## Overview

A strength-coefficient calculator for powerlifters, coaches and meet directors:

1. Enter the lifter's sex, body weight and three-lift total (squat + bench press + deadlift). Weights can be in kilograms or pounds and are converted internally.
2. The tool computes four systems in parallel: DOTS (4th-degree polynomial, 500-normalised), Wilks (the classic 1994 5th-degree polynomial), IPF GL Points (official IPF formula since 2019, ~100 = world-class) and Goodlift.
3. A progress bar shows how close the total is to each system's elite threshold, since DOTS/Wilks and GL/Goodlift use very different point scales.
4. Each formula shows its points, coefficient (where one applies) and a relative-strength tier, plus a one-line explanation of how that system works.
5. Mark Raw vs Equipped: IPF GL and Goodlift use equipment-specific coefficients, so the equipment choice changes those two scores.

Offline and deterministic: pure polynomial computation, no federation API or live data.

## Inputs

- **Sex** (select)
- **Body weight** (number): e.g. 82.5
- **Total lifted (squat + bench + deadlift)** (number): e.g. 600
- **Weight unit** (select)
- **Equipment** (select)
- **Decimal places** (number)

## When to use

- When comparing the relative strength of powerlifters across different bodyweight classes and sexes.
- When evaluating performance under different federation scoring systems, including the modern IPF GL Points and the classic Wilks formula.
- When determining a lifter's standing relative to elite strength thresholds for raw or equipped divisions.

## How it works

- Select the lifter's sex and choose the weight unit (kilograms or pounds) for input.
- Enter the lifter's body weight and their combined three-lift total from the squat, bench press, and deadlift.
- Select the equipment type (Raw or Equipped) to apply the correct coefficients for the IPF GL and Goodlift formulas.
- Review the side-by-side results showing the calculated points, coefficients, relative-strength tiers, and progress bars for all four systems.

## Use cases

- Meet directors calculating best lifter awards across multiple weight classes using DOTS or IPF GL points.
- Powerlifting coaches tracking a lifter's relative strength progression over multiple training cycles.
- Athletes comparing their raw total against equipped benchmarks to decide on competitive divisions.

## Frequently asked questions

### What is the difference between DOTS and Wilks?

DOTS is a newer 4th-degree polynomial formula designed to reduce the bodyweight bias found in the classic 1994 Wilks 5th-degree polynomial.

### Why does the equipment selection change my score?

The IPF GL and Goodlift formulas use specific coefficients for raw versus equipped lifting to account for the supportive gear used.

### Does this calculator require an internet connection?

No, it performs all polynomial calculations locally and deterministically without calling external federation APIs.

### What is a world-class score in IPF GL Points?

In the IPF GL system, a score of approximately 100 points is generally considered a world-class performance.

### Can I enter my weights in pounds?

Yes, you can input weights in pounds, and the calculator will convert them to kilograms internally for the formulas.
