Good point! Today Modeloop mostly treats signals as numeric values with optional metadata.

I probably wouldn’t want Modeloop to automatically convert between SI and Imperial units inside the model, because that can make the behavior less explicit.

What I do think is useful is documenting that a certain signal represents speed in mph, temperature in degC, pressure in psi, etc. So the value stays exactly what the model defines, but the user and generated artifacts have clearer semantics about what each signal represents.
