The Dimensions of City Blocks
From Seth Kadish's VizualStatistix: "A block is by no means a standard unit of measurement. Depending on the urban plan, blocks can be square or oblong, and can vary significantly in side length. For this plot, I measured the median length of downtown blocks in six cities that have regular grid layouts — that is, the dimensions of their city blocks are consistent. I've included blocks per mile along the outer axes, and the ratio of short to long dimension for each city. For this value, one represents a perfect square while smaller values indicate more oblong blocks."

As popular culture would have it, Catherine O'Leary's cow set the standard for Robert Moses. The three and a half square miles of blocks that burned in Chicago in 1871 were rebuilt after the great fire on a 1/6th mile/block standard.
