The step and the double step are units of length that, like the foot, existed in many nations or - like the Anglo-American yard - still exist.

step

The step as a measure is derived in Europe from the Roman gradus , which measured 2 1 ⁄ 2  pedes, i.e. a little more than 74 cm. In German-speaking countries, the step was usually between 71 and 75 centimeters. There was no longer an exact definition, as such dimensions were partly derived from the foot size of the ruling prince and sometimes corresponded to two, sometimes three feet. Within the Holy Roman Empire , i.e. the German Empire, units of measurement differed from principality to principality.

Individual dimensions for the crotch

  • China : 1 Bu = 5 field knife feet = 1.5689 meters
  • Treviso : 1 Passo = 5 Piedi / foot = 2.0405275 meters
  • Dalmatia : 1 Passo = 5 Piedi / foot = 10 Quarte = 1.73867 meters
  • Ragusa : 1 Passo = 4 Braccia = 2.0502 meters
  • Reval : 1 step = 3 feet (Russian) = 0.91438 meters
  • Castile : 1 Passo = 1 2 ⁄ 3  Varas = 1.393175 meters
  • Cuba : 1 Paso = 1 2 ⁄ 3  Varas = 1.42283 meters

In Naples there were two steps

  • 1 Passo itinerario = 7 Palmi = 1.85185 meters
  • 1 Passo agrario / field step = 7 1 ⁄ 3  Palmi = 1.9400 meters

and in Lisbon had the step

  • 1 Passo geométrico = 1 1 ⁄ 2  Varas = 7 1 ⁄ 2  Palmos = 60 Pollegadas = 1.65 meters ( 1 13 ⁄ 20  meters)

Double step

The Roman passus (double step) was 2 gradūs or just under 1 1 ⁄ 2   m, 1000 passūs resulted in the mile (mille passuum). This double step (i.e. from one foot landing to the next landing of the same foot) was and still is the basic measure of the military walking pace . Today, depending on national usage, lengths of between 80 and 160 cm are common for the (double) step, so that the parade march speed in step with the same step frequency is slightly different in each country.

In addition, there are some applications that officially use meter-based units, but many of the default values ​​have a step-based origin. For example, the traffic signs / beacons “Level crossing ahead” are on the streets at a distance of 80, 160 or 240 m - actually at a distance of 100, 200 or 300 paces, since the railway was already there before the meter became a legal unit of length in Germany.
