The developer who implemented units is a European not used to the US/imperial system. If you have a suggestion for a better description, don't hesitate. Hopefully the devs will be reading.
I had to work with both US/imperial system and metric on different projects and I remember it was always a challenge to switch from one system to another. Fortunately there are many converter websites, which provide calculators for online conversion, US/imperial system to metric and backwards.

That sounds like you don't understand just how clever the FreeCAD units system truly is.

Underneath the GUI everything in FreeCAD files always remain in default units, e.g a length is always assumed to be mm.

What the FreeCAD units system does is two things. Firstly you set the desired Units scheme, and that determines what FreeCAD shows in the GUI. Secondly input is intelligently read so no matter what Units you have set to display, you can still input ANY other units system....e.g you can have a fully metric model and display (as is the default) but then enter "1 inch" and freeCAD will convert that to 25.4mm automatically...not need for you to convert anything.

In 0.14 the Units system was not fully implemented so there were still many input widgets that were stuck in mm. But there is a units conversion tool built into FreeCAD so you can enter the other units in that, and copy paste the answer in mm. See Tools menu...Units Calculator in all workbenches.



by the way Mark, you probably already know this but if you don't, or for the record,

that is only true "by default" it is easily changed in the system settings. :)

I am not know if that is a KDE default or just a Kubuntu default.

That should be "UnitsSchema".
