Unit Converter


On this page you will find a compilation of all functions of the Unit Converter in detail. This list is sorted by the occurrence of the functions in the program. If you are interested in the first steps in dealing with the Unit Converter, you should read the help section first.

The collection is divided into the four sections Main Program, Menu, Custom Units and Options.

Main Program

The main program is generally devided into two parts. In the upper part, you can choose the category of the units and the kind of display and in the lower part, the units are shown depending on the mode. All of these things are explained in the following.

  • Category: In this box all categories of units are displayed, the pre-defined and the user-defined. To choose a category of units, simply select a category in this box.
  • Display: Here you can select how the units should be displayed. If you compare two or three units, only two or three units will be shown. In the table you can see a list of all units available. In the following, the functions of these two kinds of modes will be named as "Compare" and "Table". An overview over all available units, you can read in the section Units, how to add custom units, you learn in the section Custom Units.
  • Filter: Here you can set a global filter which reduces the range of displayed units. You can use this filter to get a better overview or to compare a number of units or categories in the table. Simply enter some characters from the unit or the category, it is not neccessary to make a difference between uppercase and lowercase letters. More than one filter can be divided by a comma like "metric,ell,mile".
  • Compare > Units: If you are comparing two or three units, you can see two or three boxes with units in the main window. Each of these boxes can be used in the same way. In the long box, you can select the unit. You can enter some characters in this box to limit the range of units, so it is easier to find a unit. In the box labeled with "No Prefix", you can select a prefix for the unit and in the box with the value, you can write a value. This value will be automatically converted to the other units - that is the conversion of the Unit Converter. With the help of the two small buttons, you can copy the value and the unit in the clipboard. The format for this can be adjusted in the menu "Settings > Options".
  • Compare > Copy Values to Clipboard and to this Box: You can enable this option to copy all values automatically in the clipboard and this box, so that you can collect some values before using them all together.
  • Table > Table: In this table all units currently available are listed. With a global filter (see above), you can limit this range of units. Select a unit to display this unit under the table, where you can change the value and the prefix of this unit and you can copy the values into the clipboard. If you change a value, the other values of the other units in the table will be updated. If you right click on one or more than one items, you can also copy this values to the clipboard or you can delete units from the table. In addition, it is possible to delete the prefixes from units or set the best fitting prefix, for example Kilo- for a value from 1000 to 99999.
  • Table > Hold Value: Normally, the value of a selected unit is displayed in the box under the table. If this option is activated, it is just the other way arround: The value of the selected value will be set to the value of the box.
  • Table > Unit for Comparisons: If you select the display with table and compare unit, you can see a box with a unit for comparisons under the table which is similar to the boxes from the general compare mode. You can carry out the same settings, so that you can set an unit for comparisons like the metre when working with lengths.


  • Program > Create User Defined Units: This menu opens a tool in which you can create custom units. In the help section Custom Units you learn everything about custom units and an overview over all functions of this unit editor, you can read in the section Custom Units on this page.
  • Program > Report Bug or Improvement: In this menu, you get some links to internet pages, on whoch you can report bugs or improvements regarding the Unit Converter. This tool and the list of units is expanded regularly, so that most of the ideas and units can be added to the tool.
  • Program > Close: With this function, you can close the tool. Remember to save all of the things you want to save before.
  • Settings > Options: Show the settings of the Unit Converter, where you can change the decimal separator, number formats or used characters. The options are explained in the section Options on this page.
  • Settings > Save Configuration: This function saves all current settings (for exampke the options) in a file with the file extension .ukg. You can load this file to rebuild the old settings.
  • Settings > Load Configuration: Loads an arbitrary configuration file with the extension .ukg, so that you can reload an old configuration.
  • Settings > Current Configuration as Start-Configuration: Saves the current configuration as auto.ukg in the application folder. The Unit Converter searches for this file when starting and if the file exists, this settings are loaded. So, you can create a start configuration with this function.
  • Settings > Save Configuration automatically: If this option is enabled, the last configuration of the tool is saved as auto.ukg when closing the tool, so that the last setting can be reloaded when starting the converter for the next time. So, you do not have to care about saving any settings if you are using this function, because the program will be started like you have closed it.
  • Settings > Language: Here you can change the language of the Unit Converter. Remember the different names of units in different languages.
  • Info: Here you get some information regarding the program, other programs, the licence and a help section.

Custom Units

This is the editor in which you can create custom units. You can show this editor by using the menu "Program > Create custom Units". In the help section Custom Units, there is a detailed introduction to this topic, where you can also read about creating unit lists with a normal text editor.

  • Category: Here you can choose a pre-defined category, in which the new units should be attached. If you would like to attach the new units to a new category, you can enter an arbitrary name in this box to create a custom unit.
  • Table: In this table all custom units of a selected category are displayed. Pre-defined units are not shown. You can sort the table according to one of the columns and you can delete selected items with the key DEL.
  • Attach new Unit: In this box, you can enter names, shortcuts, systems and terms or factors for your new units.
  • Add Unit: If you have filled out all boxes, you can add the unit to the table with this button.
  • Save Category: Saves the units of the current table in the selected category. If the appropriate file exists, this file will be overwritten with the new one, so that comments in this file will be lost. After saving, the units will be available in the main program.
  • Cancel: With this button, you can close the unit editor without saving the current unit list.


Over the menu "Settings > Options", you can reach the options, where you can adjust some settings regarding the used formats. Another section deailing with this topic, you can find in the help section Settings.

  • Formatierung der Zahlenwerte > Einfach: Formatiert die verwendeten Zahlenwerte als normale Zahl, die so kurz wie möglich ist, also zum Beispiel 120, 12,78 oder 1 statt 120,000, 12,780 oder dergleichen. Wenn die Zahl zu lang wird, wird eine Schreibweise mit Exponent verwendet, also zum Beispiel 1,78E19. Sie können außerdem einstellen, wie viele Stellen der Exponent haben soll, also beispielsweise zwei (1,78E19) oder drei (1,78E019).
  • Format of the Values > General: The values are formated as normal number, as short as possible, for example 120, 12.78, or 1 instead of 120.000 or 12.780. If the resulting number is to long, an exponential format like 1,78E19 is used. In addition, it is possible to set the number of exponent places, for example two (1,78E19) or three (1,78E019).
  • Format of the Values > Fixed Length: A fixed length for numbers is used. When formating with three decimal numbers, the numbers will look like 1,000 and with two decimal places 1,00 independent from whether the number could be represented in any shorter way. Behind the option, you can set the digits before the point. If this number is not high enough to represent the value, an exponential format is used.
  • Format of the Values > Scientific: The scientific format always uses the exponential format, for example 1,23E3 instead of 1230 and so on. Again, it is possible to set the places of the exponent.
  • Format of the Values > Each with this Number of Decimal Places: Here you can set the number of decimal places used in all of the formats. In the general mode, this number only is used if neccessary, in the fixed mode at every value.
  • Format of the Values > Set Prefixes automatically (1000 m -> 1 km): If this option is enabled, in the table view and in the compare view, prefixes will be set automatically whenever values are smaller than 1 or greater than 1000. For example, 1000 m will be rewritten to 1 km. If this option is disabled, an exponent will be used if the values are to great, for instance 1E21.
  • Format of the Values > Use Fractions (0.3333.. -> 1/3): If this option is enabled, fractions are used in the converter if possible, for example 1/3 instead of 0.3333.. . If this option is not enabled, only floating point values like 0.33333.. will be used.
  • Format of the Units > Characters between: Here you can set arbitrary characters which will be used between the value and the unit (1,00Xkg), the prefix and the unit (1,00 NanoXKilogram) and between the prefix and the shortcut (1,00Xkg). A possibility is to use blanks (1 kg) or do no enter anything into the boxes (1kg).
  • Format of the Units > Cut Unit after this Character: Often, more than one name is defined for a unit, for example Mile/Meile. If you set a character here, for example /, only the word Mile is copied. With this option, you can also write some comments behind some units and these comments will not be copied.
  • Format of the Units > Prefer Shortcut or full Names of Units: Depending on your settings in this section, the unit is copied with the shortcut (1 kg) or with the full name of the unit (1 kilogram). If no shortcut is defined, the full name is used in each case.
  • Decimal Separator: Depending on the system, a point (1.0) or a comma (1,0) is used as separator. Pre defined is the separator of your system, but you can also use the other one.
