------------------
Such things are - not unusually - the preserve (or problem) of history
of
cartography as well as map cataloguers, and you will find a web-page for
obsolete scales and their conversions to RF on the History of
Cartography
gateway site : [http://ihr.sas.ac.uk/maps/]; or try 'Oddens bookmarks' -
a
parallel cartography gateway site [http://oddens.geog.uu.nl/index.html].
One or other of these sites has a contribution to this problem by Geoff
Armitage, Brit. Libr., Map Libr.

If it helps, try this first ('Mathematical data for bibliographic
descriptions of cartographic materials and spatial data'):-

Jessica,

There are at least two good websites that convert these
kinds of distances for you online. I am responding from home
so do not have the URLs at my fingertips, but if nobody else
has responded to your question by Monday morning I'll send
them to you. When you do the calculations the final scale
statement should read:

Scale [ca. 1:XX,XXX]

or something similar.

Sincerely,

Paige Andrew
