Cubic rod

from Wikipedia, the free encyclopedia

The cubic rod was a measure of space before the introduction of the metric system. The length, width and height of the rod were taken as the basis of measurements . Since the rod, the foot and the inch have their respective values ​​for each region, the specification in the metric system does not make sense. The list is drawn up for the decimal division. For the 12 division, the duodecimal system , see at the end of the page.

  • 1 cubic rod = 1 rod by 1 rod by 1 rod = 10 manhole rods = 100 bar rods = 1000 cubic feet
  • 1 manhole rod = 1 rod by 1 rod by 1 foot = 10 bar rods = 100 cubic feet
  • 1 bar rod = 1 rod by 1 foot by 1 foot = 10 cubic feet
  • 1 cubic foot = 1 foot by 1 foot by 1 foot = 10 shaft feet = 100 joist feet = 1000 cubic inches
  • 1 manhole foot = 1 foot by 1 foot by 1 inch = 10 joist feet = 100 cubic inches
  • 1 joist foot = 1 foot by 1 inch by 1 inch = 10 cubic inches
  • 1 cubic inch = 1 inch by 1 inch by 1 inch = 10 shaft inches = 100 beam inches = 1000 cubic grains
  • 1 shaft inch = 1 inch by 1 inch by 1 grain = 10 bar inches = 100 cubic grains / cubic line
  • 1 bar inch = 1 inch by 1 grain by 1 grain = 10 cubic grains
  • 1 cubic grain = 1 grain by 1 grain by 1 grain = 10 shaft grain = 100 bar grain = 1000 cubic scruples

Schachtgran, Barkengran, cubic scruple and the types of the second scruple are grouped accordingly in the row, but were rarely used. In the duodecimal system the relationships were:

  • 1 cubic rod = 12 manhole rods = 144 bar rods = 1728 cubic feet
  • 1 manhole rod = 12 beam rods = 144 cubic feet
  • 1 bar rod = 12 cubic feet

...etc

  • 1 bar inch = 12 cubic lines
