Did You Know?
The word "mile" comes from the Latin mille passus, a thousand paces. A Roman pace wasn't one footstep though, it was a full left-right stride cycle, so a Roman mile actually worked out to around 2,000 individual steps, the same ballpark this calculator uses today.
At its peak, the Roman road network stretched over 250,000 miles, with stone milestones planted every thousand paces so army commanders could calculate march times. It's one of the earliest large-scale uses of a standardized steps-to-distance conversion.
