About

⚽ FMInside Attribute Normalizer - Classic FM Scale

Bring back the classic Football Manager attribute scale to FMInside.net!

What Does This Extension Do?

FMInside changed their player attribute display from the classic 0-20 scale  to a new 0-100 scale. This extension instantly converts all player attributes back to the familiar 0-20 format that FM veterans know and love.

Why You Need This

If you've been playing Football Manager for years, you instinctively know what a "16 Pace" or "18 Finishing" means. The new 0-100 scale (80 Pace, 90 Finishing) disrupts this muscle memory and makes it harder to quickly evaluate players.

This extension solves that problem with one click.

How It Works

1. Install the extension
2. Visit any FMInside player page
3. Click the extension icon in your Chrome toolbar
4. Toggle ON to see attributes in 0-20 scale
5. That's it! All player attributes are instantly converted

Example Conversions

- 95 → 19
- 90 → 18
- 85 → 17
- 80 → 16
- And so on...
