Editors' Review

by   / February 27, 2009

This handy and free utility quickly converts almost every unit of measurement under the sun into other units. Quad-Lock Unit Converter is not just small, but it's also time-efficient, as no installation is required other than clicking on the EXE file. When determining conversions, you first select from a long list of subjects, including ones for area, charge, temperature, mass, density, and thermal conductance. If you don't regularly work with, say, viscosity, you can remove it from the main window. You then choose your source and desired units, such as feet to centimeters. After that, you simply type in a specific number, and this application will convert it to your desired unit in mere seconds. Quad-Lock Unit Converter also provides quick access to a scientific calculator, but that's about the only extra you'll find. Whether you're a scientist working out complex equations or a traveler who's baffled by the metric system, this freebie can help you out of a bind.

Full Specifications

What's new in version 5.4

* Added ability to perform coordinate transformations from latitude/longitude to UTM (and vice-versa). * Added Heat Flux conversion category with 25 units * Added Magnetic Flux conversion category with 14 units * Added Volumetric Heat Generation category with 11 units * Added 6 new units to Fuel Consumption category (non-linear conversions such as Liters/100km to Miles/Gallon) * Corrected conversion factor in Amount of Substance; 1 mol = 1000 mmol, showed 1000000 mmol * Re-organized main menu. Also, added an icon next to each menu item. * Quad-Lock Converter now uses Unicode for the entire program (UI controls and the engine), enabling internationalization. * Removed restrictions such that users can now add an un-limited number of custom units and categories. Furthermore, users can also add non-multiplicative unit conversions (such as from Liters/100km to Miles/Gallon) * Changed location of UnitConverter.ini (preferences file) to the %APPDATA%\UnitConverter folder or, if running from a removable drive, to the removable drive's root folder (e.g. F:\UnitConverter.ini). * User defined custom categories can now be rendered visible or invisible in the main window using Main Menu > Edit > Preferences * The conversion engine now uses a hash table to efficiently map unit names to associated conversion factors. This should improve speed on old and obsolete computers (the difference may not be noticeable on fast modern computers).
