Revision Plasma 5.26 (2022-06-23)

On this page you can set your preferred languages and formats for the Plasma™ Workspace and Applications to be displayed in.

In most cases, you can simply select the language, and all options will be set in an appropriate manner. The Plasma™ Workspace and KDE Applications are written in American English and are translated into many different languages by teams of volunteers. These translations need to be installed first before you can choose to use them.


Ensure that you have installed the Plasma™ language packages or translations for the languages you want to use.

As Plasma™ is build upon the Qt™ libraries, you need the Qt™ translations for the selected languages as well to have a fully localized GUI.

On each selection bar you can see examples how the settings look like and which measurement units are used. In addition to numbers, you can see how currency values, dates, and times in long and short format are displayed. When you change any of the settings, the preview shows the effects of the changes before you apply them.

Clicking on the Add more... button on the language sub page will show you the list of available languages and will initially show your currently selected language. If the selection shows No Language Configured then you have not set a country and are defaulting to the language set by the system, normally C. If the language you want to use is not shown in this list then you will need to install it using the usual method for your system.

You can remove a language from the main list by selecting it and then clicking on the icon. You can change the order of preference in the list by selecting a language and clicking on the icon.

In case you need different individual format settings, you can select the locale for Numbers, Time, Currency and Measurement Units.


Previously, Language and Formats are independent settings. Since Plasma™ 5.26, they were merged into this KCM called Region And Language. Changing a language does automatically change the settings for numbers, currency etc. to the corresponding country or region. However, this change does not break the old configuration. The configuration file still located at ~/.config/plasma-localerc .
