I mean the legal definition of the inch is 25.4 mm. All other imperial length units are derived from the inch. Furthermore, there are more than one definition of the inch. If he worked on astronomical data from the 19th century UK, all these units would have to be changed. By tying the foot to the inch he'd only have to redefine the inch to the old British inch. |
