About this extension
Quantix

Quantix is a lightweight, responsive utility calculator and comprehensive unit converter designed to work natively as a web application, a Google Chrome Extension, or a Mozilla Firefox Add-on.

The application emphasizes offline reliability, standard keyboard and numpad accessibility, and efficient layout scaling across desktop and mobile form factors.



Features

1. Interactive Core Utilities
  • Calculator: A standard-precision arithmetic calculator supporting sequential equations, numeric storage states, and automatic floating-point rounding.
  • Age Extractor: Generates an exact tracking breakdown of age in years, months, and days based on a selected birth date.

2. Physical & Scientific Converters
  • Currency Converter: Connects to dynamic exchange rate services, featuring real-time input filtering and an automated local cache fallback for offline operation.
  • Physical Dimension Converters: Support for conversions across several unit groups, including:
  • Length / Distance
  • Mass / Weight
  • Temperature
  • Volume
  • Area
  • Speed
  • Time

3. Navigation & Usability
  • Accessibility & Keyboard Support:
  • Calculator: Full physical numpad mappings, including Backspace, Enter (evaluation), and Delete/Escape (clear/AC).
  • Shortcuts: Use the S key or Ctrl + S sequence globally to trigger unit swaps on any active converter view.
  • Arrow Keys: Use Left/Right or Up/Heigh arrow keys to switch active panels when focus is not inside an active text input.
  • Manual Theme Overrides: Seamless switching between Dark and Light mode themes that store preferences and complement native system-level visual preferences.
  • Responsive Layout: Replaced unstable vendor size classes with dynamic viewports (100dvh) to prevent mobile UI clipping from shifting browser address bars.
