Why is 22 yards called a chain?
History and usage The chain was originally called an “acre’s breadth”, because it was the width of a acre, while a furlong was the length. Edmund Gunter, a clergyman and mathematician, invented a measuring device called a chain. The chain was 66 ft (20 m) long. It was divided by 100 in small metal links.

This i’s natural, because a 25-metre chain upsets the decimal theory, and a 50-metre chain is too clumsy. The length of a 20-metre chain in feet and decimals is 65.618. Gunter’s Chain is exactly 66 feet long, just all the difference for convenience of 0.382 foot.
Why a grove is cut on the handles of chain?
To enable the reading of fractions of a chain without much difficulty, tallies are fixed at every meter length for chains of 5 and 10 m length. To facilitate holding of arrows in position with the handle of the chain, a groove is cut on the outside surface of the handle.

How do you calculate slope correction?
Cs = the total correction for slope. = l – l (1 – h2 / 2l2 – h4 / 3l4 – etc..) in which l = the length of the slope : 0 = the angle of the slope. Examples 1: – A line was measured with a steel tape which was exactly 30m long at 18oC and found to be 452.343 m.

How do you calculate chain pitch?
To count the number of pitches in a strand of chain, we would start our count from the first pin on one end of the piece of chain and move to the next pin, which would be one pitch, and then on to the next pin, which would be another pitch, and so on until the end of the strand of chain is reached.
What is chain pitch?
In terms of conveyor chain, pitch is usually defined as the distance between links, as measured from the center of the roller pin on one link to the center of the roller pin on the next link. Note that some precision link conveyors refer to the pitch as the link size.
