one issue with using only one unit for a tag is that they can’t always be transformed without rounding. E.g. maxspeed=55mph cannot be converted to kph without losing information 

Also, shorter notations are better readable, hence reduce the likeliness of errors not noted. 

On the other hand, I agree in the example of voltage it would make it easier for queries to use the same unit. (you still can make queries, but they are more complicated if you have to take units into account)
