It's about one-seventy-thousandth as long as Hadrian's Wall
In other words, the length of Hadrian's Wall is 71,000 times 0.0017 kilometers.(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 120 km (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 250,000 times as long as a Red Blood Cell
In other words, the length of a Red Blood Cell is 0.00000430 times 0.0017 kilometers.(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 one-two-hundred-fifty-thousandth as long as The Grand Canyon
In other words, 0.0017 kilometers is 0.000003810 times the length of The Grand Canyon, and the length of The Grand Canyon is 262,000 times that amount.(a.k.a. Gran Cañón) (Arizona) (Colorado River miles measure)
The Grand Canyon has a total length of 446 km 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 1.10 kilometers above the floor of Granite Gorge.
It's about 300,000 times as long as a Cell's Nucleus
In other words, 0.0017 kilometers is 280,000 times the length of a Cell's Nucleus, and the length of a Cell's Nucleus is 0.00000360 times that amount.(for animal cell)
The nucleus of an animal cell measures an average of 0.00000000600 kilometers. The nucleus is the largest organelle in these cells, accounting for about 10% of the cell's total volume.
