You best bet would probably be to use kilograms.
I would use the metric unit is inches
meters
The precision is 0.05 metres.
There is no such thing as a "metric unit" for a door. If you mean measurement, you would use either metres (m), decimetres (dm), centimetres (cm), or millimetres (mm). There are 10mm in 1cm, 10cm in 1dm, and 10dm in 1m. Metres converted to the smaller units are as follows: 1000mm, 100cm, and 10dm. Some examples of door measurements in the different units are 1.9m, 19dm, 190cm, and 1900mm (dm is the least used of these four, cm and m the most common, and mm are usually only used on small objects).
They have to calculate the weight of the door so they know how heavy it is.
In the USA, inches is the best to match a door to one in the store. cm is more precise in any application, but won't help you in finding a door.
The replacement door handle bolts are metric sized. The standard bolts are not.
Best thing to do is look at the sticker on the driver door jam or door and read the g.v.w the gvw is not the curb weight, it is the max weight of the vehicle including passengers and luggage
