The nautical mile is the standard unit of measurement on a chart. Every
minute of latitude equals a nautical mile- (not longitude, for reasons
that are apparent when considering a globe). Of course we are all aware
that a knot equals 1nm/hr.

Not necessarilly. Great Lake charts are in statute miles and use Poly
Conic projection, rather than the Mercator that the off shore charts
use.
Learn something new everyday.
