About this conversion
Rome measured with the pes (about 0.296m, slightly shorter than a modern foot), five pedes made a passus (about 1.48m), 120 pedes an actus (about 35.5m) and 1,000 passus a mille passus (about 1.48km, whence 'mile').
These values come from surviving pes standards and milestones measured by archaeologists, so they are scholarly averages.
