Mike: I don't know of an exact definition.
City blocks certainly vary. In general, they're just a guide to getting around (go so many blocks in this direction, turn right, then so many blocks in that direction, ...) . In New York, it's the distance between adjacent numbered streets (short blocks) or avenues (long blocks, as the avenues are much further apart). Chicago city blocks tend to be more uniform. In California, the term isn't used very much. I think a football field is a little over 90 m or so. A story (no e in American English) varies, depending on whether it's a standard residence, a commercial building, or whatever. For houses, the minimum is a little over 2.5 m. For fancier houses, it's somewhat more.
