Convertigo par Anthony

Convertigo automatically scans every page you visit for measurements and currencies, highlighting detected values with a subtle underline. Hover over any highlight to see its conversion in a popup, or hold a key (Alt, Ctrl, or Shift) to instantly replace every detected value on the page with its conversion at once.

You can also select any text containing measurements or currency amounts and a popup appears in the corner with all detected conversions.

Handles fractions ("1/2 inch"), mixed numbers ("1 1/2 cups"), dimension strings ("6x4ft"), ranges ("5-10 km"), and ambiguous units like oz (shows both mass and fluid). Results auto-downscale when appropriate for example 0.5 kg displays as 500 g.

Configure your preferred unit system, temperature scale, target currency, and more from the settings popup. Units already in your preferred system are skipped so you only see what's useful.
