J Richardson also notes:

Uh, in addition to above, Graphic Standards lists these other drawing scales:
1:2,500
1:5,000
1:10,000
1:25,000
1:50,000
1:100,000
1:4,800 (1" = 400')
1:10,560 (6" = 1 mile)
1:12,000 (1" = 1,000')
1:21,120 (3" = 1 mile)
1:24,000 (1" = 2,000')
1:63,360 (1" = 1 mile)
1:126,720 (1/2" = 1 mile)


Speaking of which,
in the Dept. of Whimsy:

For the ocean sailors, (who know that 1 nautical mile = 6,080.27 feet):
1:72,963.24 (1" = 1 nautical mile)

For the mountaineers out there, who know better than I do the height of the tallest mountain in North America: 1:243,840 (1" = 20,320' eg, approximately one *Denali*)
