On the avenues, it's 20 street blocks to the mile: in other words, from West 4th Street to West 24th Street up/down Sixth Avenue is exactly a mile. Don't remember the distance of the (cross-town) avenue blocks: seems to me though it is a third of a mile, in other words from Lexington to Sixth (Lex-Madison-Fifth-Sixth) would be a mile. When I lived in Chelsea later in the '60s and 1970, I did calculate it once: I figured I walked at least a mile a day catching the trains to and from work, then maybe a couple miles more on the nights I walked down to the Village to the Lion's Head, more still when I walked over to the Lower East Side to Stanley's.
