:I don't see where WP:MOSNUM says not not link. In fact it says to link ambiguous units, although I'll admit that these units aren't ambiguous, just relatively unknown and deserving of a link, IMO. These aren't common units to anyone other than sailors and perhaps aviators. And if the MOS forbids a link in a conversion then why is it so easy to add such a link to the template? I'm happy to have you and your bot clean up conversions and the like, but I'm not going to abbreviate things in the interest of standardization when it takes more trouble to add the command to abbreviate (I write all of my conversions manually) than is gained by doing so. Thus I'll never abbreviate feet, meters and the like.
