  description

  Ever stared and thought, “What the hell is a kilometer?”
  
  This lightweight extension lets you instantly convert currencies and values anywhere on the web. Just pick your preferred currency, highlight any price, and get a clean pop-up with the converted value. No tabs, no calculators, no time lost.
  
  It handles:
  - All major (and plenty of obscure) currencies
  - Messy formats, weird spacing, symbols, and even text-based prices
  - Temperatures, Lengths, Weights!
  
  Fast, simple, and actually useful.
  
  Free to use. No shady stuff.
  Built because I needed it myself.
