Unit Converters

Cactus2000 offers more than 120 unit converters and other calculators from physics, chemistry, meteorology, geometrie, money, date and time and miscellaneous. There is a choice from unit converters for classical problems like temperature units to special problems like measures of air pollutants. In addition there are calculators for frequently needed calculations like the calculations of percents and areas. Here is an overview:

  • All converters are written in JavaScript. Therefore they might be used again and again without reloading the webpage.
  • With Cactus2000 converters you see the input value and the result for many units at the same time.
  • Only the most frequent units are considered to preserve overview.
  • More than 120 unit converters and similar tools are available.
  • With copy/paste-functions, e.g. Cntr-C/Cntr-V you may exchange data between Cactus2000 converters and other applications.
  • All of them are available as popups also. These are very handy when many windows are open on the screen.
