Around the world, Mettr (Mett 
, Mettr 
) is a rare primarily masculine, but scarcely female given name. The forename Mettr is characteristic of Hong Kong, where it is a rare masculine name, Indonesia, where it is a very rare male name, and Italy. Not in comparison with a country's population, it most frequently occurs in Indonesia, Hong Kong, and the United States. More prevalently, Mettr is the last name as well as the forename.
