Perche (unit)

from Wikipedia, the free encyclopedia

The perche was a measure of length in France , Italy and Switzerland . In Belgium it was the decameter . It corresponded to the rod and had different lengths for different uses. This also had an effect on the area, the arpent . 100 square perches, which corresponded to an arpent, had between around 34 and 51 ares .

After the meter was defined to be exactly 443.296 Parisian lines in length in 1799 , the Parisian foot had a length of exactly 4500 ⁄ 13.853 meters (≈ 32.48 cm).
Previously, the measure was subject to regional fluctuations, and accordingly the measures derived from it.

In France a distinction was made

  • 1 perche as a field measure rod = 18 feet = 2592 Paris lines = 81,000 ⁄ 13,853 meters ≈ 5,847 meters
  • 1 perche as a land measure rod = 20 feet = 2880 Parisian lines = 90,000 ⁄ 13,853 meters ≈ 6,497 meters
  • 1 perche as a forest measure rod = 22 feet = 3168 Parisian lines = 99,000 ⁄ 13,853 meters ≈ 7.146 meters

The perche was measured at 22 feet when it came to state domains (la Perche des cauxet forets) On the island of Bourbon , the measure varied between 18 and 20 pieds (feet)

A similar distinction was made in the Swiss canton of Neuchâtel , but with different values:

  • 1 perche de champ (field rod) = 16 pieds de champ ≈ 4.5944 meters
  • 1 Perche de vigne (vineyard rod) = 16 Pieds du pays ≈ 4.69213 meters

In Italy, the Perche in Pisa ( Grand Duchy of Tuscany ) was used to survey the field. In general, the perche was the canna and a perche had mostly eight palmi.

  • 1 Perche = 5 Bracci = 60 Crazie = 20 Soldi = Quatrini = 240 Denari ≈ 1293.75 Parisian lines about 2.838 meters (calculated from 1290 Parisian lines ≈ 0.0473 meters per Crazia )
