As we know that we are living in different country, and each country use different measuring units.
Some of them already handle in settings
Temperature: C and F. Seems handled in the widget
Pressure: bar / psi. Seems handled in the widget
Distance: KM / Miles. Not all widget display follow. When I using miles, some of the widget still displaying km
Volume: Liter / Gallon (UK / US) : no option to set, which is now make some measurements is unknown using which, like mpg (miles per gallon, is that currently using UK or US gallon?)
The following picture is showing some widget is still using km when i have set mile in settings.
