A pace is a unit of length consisting either of one normal walking step (approximately 0.75 metres or 30 inches), or of a double step, returning to the same foot (approximately 1.5 metres or 60 inches).
[1] The word "pace" is also used for units inverse to speed, used mainly for walking and running, commonly minutes per kilometer.
[2] The word "pace" is also used to translate similar formal units in other systems of measurement.
[3][4] The Ancient Roman pace (Latin: passus) was notionally the distance of a full stride from the position of one heel where it raised off of the ground to where it set down again at the end of the step: two steps, one by each foot.
[7] The double pace (βῆμα διπλοῦν, bḗma diploûn), meanwhile, was similar to the Roman unit, comprising 5 Greek feet.
