How do I scale city blocks?

I'm not quite sure how to ask this... but anyways...

I have a plane that I want to become a very simple city. By simple, let's just say at this point that all I'm concerned about is having a grid of city blocks. The center of the city is at the center of the plane (0,0,0).

Let's say I want one city block to equal one mile. What is the best way to scale this (code-wise)? Or is it completely arbitrary?

For example, should one side of a city block simple be of length "1", "100", or "1000", etc.?

I'm not sure if it's clear what I'm asking. But the bottom line is I'm not sure what I should use for a representative scale in Unity... or if it even matters, for that matter!


Unity units are 1 = 1 meter, so you could use real measurements.

Personally, I don't think it matters (Unless your making some sort of "realistic" game), but I usually try to use the smallest even number that looks good... So, for a city block (with buildings) I would probably try something around 500...
