Sorry, being cryptic and facetious. I (and a lot of other forumists) don't understand metric dimensions in connection with pre-war British cars, they're usually used naturally by people who went to school after 1972.
The metre was rumoured to be the length of a former French Kings arm, although it was officially defined in different terms.
