Historical Note on Leuca
The leuca was defined as $1500$ paces, which itself was a double step, and is something like about $5$ feet.

Thus a leuca was about one (statute) mile and a half.

Compare this with the Roman miles passuum, which is literally $1000$ paces.

The word is similar to league, which in its modern definition is $3$ (statute) miles.
