Unit Converter - Easy Conversion of Measurements

Unit Converter Screenshot

Quad-Lock Unit Converter is a freeware tool that can take care of all your unit conversions within seconds. It contains more than 1000 units of measurement commonly encountered while solving engineering or everyday conversion problems. It includes a Search function to quickly find units, support for adding custom units, and a smart input box that evaluates calculations & complex expressions. Only the most common units are visible by default (e.g. Area, Distance, Temperature, Velocity) but hundreds more are included and easily found using Search.

Distinctive Features:

  1. Simple & clean user-interface makes the learning curve non-existent to convert most measurements under the sun, even for inexperienced computer users.
  2. Fast and time efficient. There is no need for an installation package, no splash screen, and no silly registration or survey forms. The program is launched in less than a second, a Search function makes it easy to find any unit (even hidden ones), and conversions are performed instantly while typing input.
  3. The program can be run from a USB drive as a completely portable application, without leaving any personal data or registry settings behind.
