A United States dime coin is 1.35 mm thick. See related link.
There is only one metric system. The relevant units, within that system would be millimetres.
A millimeter is closest in thickness to the thickness of a credit card or the edge of a dime.
A dime does not have weight in meters, as weight is typically measured in grams or ounces. However, if you are asking about the thickness of a dime, it is approximately 1.35 millimeters.
The thickness of the US dime is 1.35 millimeters. That's the same as 0.00135 meter, or 0.00000135 kilometer. You could use whichever of those you like, to remember the thickness of a dime or discuss it with other people. They're all correct. But the millimeter produces the most convenient number.
Measuring the thickness of a dime in kilometers would be impractical because a kilometer is a unit suited for measuring long distances, not small objects. A dime's thickness is only about 1.35 millimeters, which is much better expressed in millimeters or centimeters for clarity and precision. Using kilometers would result in an awkwardly small decimal number, making it harder to understand and communicate the size effectively. Thus, choosing the appropriate unit for the measurement context is essential.

either a decimeter or a millimeter...
No, a dime is closer to .045. But that will also depend on how old the dime is. An old dime will not have the same thickness as a new dime.
The actual thickness of a dime is between 1.35 and 1.40 mm.

Why, dime, of course! ---- Indeed, as the word "dime" means "tenth" anyway.
