[Feature Request] Units used - Metric System/Imperial Units

[NEKolev]

It would be good to add a parameter, which is the unit of measurement used by default Metric System/Imperial Units - gram/troy ounce, millimeters/inches. It will be good for each coin to be able to change the default units. Reports will need to be redesigned to show the chosen unit of measurement - Metric System/Imperial Units or preferably both.
