What is the Power-to-Weight ratio (W/kg)?

It is a metric used in endurance sports like cycling to compare power output relative to body mass. It is calculated by dividing Watts by Kilograms.

Which scoring systems are supported for powerlifting?

The tool supports DOTS, WILKS, and IPF points to normalize strength across different weight classes.

How can I see my performance tier?

Use the `get_performance_rank` tool with your calculated metric value and sport type to see if you fall into Elite, Advanced, Intermediate, or Novice categories.
