New in Quad-Lock Unit Converter 5.4 (Jul 23, 2009)
- 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).
