You can't change the units of Indicators or Controls at Runtime. What
we did to get around that is using unit-less indicators, displaying the
caption of the indicator and changing it in runtime, e.g. switch
caption between "Temperature [°C]" and "Temperature [K]" when the user
toggles the units.
You can still use the unit conversion functions to convert between the
different units. For example, if you get the temerature from a sensor
in K, you can use convert to "K" (to assign the unit) and then convert
using "degC", which will return a unit-less number in °C.
