    That makes sense: 12 lignes to the inch; 12 inches to the foot: magnitude of ten.

    Unless you're a surveyor, in which case there are only ten inches to the foot.

    I don't recall, did anyone mention the furlong–firkin–fortnight system (https://en.wikipedia.org/wiki/FFF_system)? A microfortnight is rather close to one second and a millifurlong is almost 8" (or 20cm).
