Unit Converter is a freeware tool that can take care of all your unit conversions even when offline. It has an easy-to-use interface and contains most of the units commonly encountered while solving engineering problems. With more than 400 units, you are likely to find the units you are looking for. Other features include the ability to add user-defined conversions. Everything is built into a single executable file so no uninstaller is necessary. Its small file size makes it easy to distribute among friends and co-workers.

Version 5.0 includes unspecified enhancements and bug fixes.
