The English Channel measures between 702,000 shaftments, narrowing as it flows northeast. The world speed record for a Channel crossing by swimmer was set by Australian Trent Grimsey in 2012, with a time of 6 hours, 55 minutes.
It's about one-ninety-thousandth as long as The 405.
In other words, 8.50 shaftments is 0.0000111150 times the length of The 405, and the length of The 405 is 89,969 times that amount.(a.k.a. I-405, Interstate 405, San DIego Freeway) (Southern California)
Running from Irvine to San Fernando, The 405 runs a total of 764,700 shaftments. The 405 is the most heavily-trafficed freeway in the United States, with an average speed as low as 8 kph during rush hours.
It's about one-ninety-thousandth as long as Hadrian's Wall.
In other words, the length of Hadrian's Wall is 91,000 times 8.50 shaftments.(a.k.a. Roman Wall, a.k.a. The Wall, a.k.a. Vallo di Adriano, a.k.a. Vallum Aelium, a.k.a. Severus' Wall) (from North Tyneside, Tyne and Wear, England, United Kingdom to Cumbria, North West England, United Kingdom)
Hadrian's Wall, which crossed England form the North Sea to the Irish Sea during the time of Roman rule, measures 790,000 shaftments (about 79 Roman miles). Roman soldiers — at one time up to 10,000 of them — only occupied Great Britain for about 246 years after the wall was built, after which time the local Brits began to take residence the wall's garrisons.
It's about 150,000 times as long as a Red Blood Cell.
In other words, the length of a Red Blood Cell is 0.00000590 times 8.50 shaftments.(a.k.a. RBCs, a.k.a. haematids, a.k.a. erythrocyte, a.k.a. erythroid cells, a.k.a. red blood corpuscles) An average Red Blood Cell measures 7.5 µm (micrometers) in diameter. An average human has 20 - 30 trillion red blood cells in their body and each cell completes a circulatory lap in about 20 seconds.
It's about 200,000 times as long as a Nucleus (Cellular).
In other words, 8.50 shaftments is 220,000 times the length of a Nucleus (Cellular), and the length of a Nucleus (Cellular) is 0.00000450 times that amount.(for animal cell)
The nucleus of an animal cell measures an average of 0.0000390 shaftments. The nucleus is the largest organelle in these cells, accounting for about 10% of the cell's total volume.
It's about one-three-hundred-fifty-thousandth as long as The Grand Canyon.
In other words, the length of The Grand Canyon is 345,000 times 8.50 shaftments.(a.k.a. Gran Cañón) (Arizona) (Colorado River miles measure)
The Grand Canyon has a total length of 2,930,000 shaftments along the course of the Colorado River at its bottom. Having opened in early 2007, the Grand Canyon Skywalk allows tourists to stand on a horseshoe-shaped glass walkway 7,220 shaftments above the floor of Granite Gorge.
It's about 650,000 times as long as an E. coli Bacterium.
