The "old London mile" was 5000 ft., and probably this was the mile which was modified to 5280 ft., or 8 **furlongs**, and so became the British statute mile.

It was therefore equal to 79,200 in., and divided decimally into 10 **furlongs** 100 chains, or 1000 fathoms. For the existence of this fathom (half the Belgic pertica) we have the proof of its half, or yard, needing to be suppressed by statute (9) in 1439, as "the yard and full hand," or about 40 in., -- evidently the yard of the most usual old English foot of 13.22, which would be 39.66.
