ConvertThat! is a unit converter with a cheeky twist. Of course, it converts units for you, but then it speaks out, tells you awkwardly silly jokes. It also has plenty of unique units for you to convert to, like Empire State Buildings and Wembley Stadiums. And if you're worried you may get annoyed with the converter's witty remarks, don't worry -- you can always turn them off, or reduce their frequency, in the settings. Don't think it's awesome yet? Just try it out!


  • Easily convert between units in different subjects
  • Convert unusual units like Olympic Pool lengths and the volume of the Wembley Stadium
  • Enjoy converting with fun attitude and some cheeky jokes (or turn those off)
  • Bringing the fun back to unit conversion (as if it wasn't fun before...)
