It's about 650 times as long as a London bus.
In other words, 5,642,000,000 microns is 673 times the length of a London bus, and the length of a London bus is 0.00149 times that amount.(Routemaster Double-Decker, RM standard specification)
The Routemaster Double-Decker buses, well-known as icons of London, measure 8,380,000 microns in length. The buses were said to be well-designed for travel in the London traffic, as they offered an open door for riders to board and exit even while the bus was moving at low speeds, and a full-time conductor to collect fares.

Interstate 80, crosses the continent of North America from Teaneck, New Jersey to San Francisco, California and covers a total length of 4,638,030,000,000 microns. A 60,000,000,000 microns stretch between mile marker 318 in Grand Island, Nebraska and mile marker 390 in Lincoln, Nebraska is the longest straight path in the US Interstate system.
It's about 900 times as tall as a Giraffe.
It's about one-one-thousandth as long as The Great Wall of China (wall only).
In other words, 5,642,000,000 microns is 0.0009014 times the length of The Great Wall of China (wall only), and the length of The Great Wall of China (wall only) is 1,109 times that amount.(长城, 長城, Chángchéng, a.k.a. 万里长城, 萬里長城, Wànlǐ Chángchéng) (a.k.a. "The long wall of 10,000 Li") (from Shanhaiguan through Lop Nur, China) (wall segments only)
The Great Wall of China has total wall segment length of 6,259,000,000 microns. Built and maintained in multiple sections over about eleven centuries, the Great Wall is currently suffering the effects of erosion, especially in the older sections made primarily out of mud.
It's about one-one-thousandth as long as The Amazon River.
In other words, 5,642,000,000 microns is 0.0008765 times the length of The Amazon River, and the length of The Amazon River is 1,141 times that amount.(from Nevado Mismi, Arequipa, Peru through near Marajó, Brazil) (approximate distance)
The Amazon River has an approximate distance of 6,437,000,000,000 microns. Although by most measures it is the largest and one of the most significant rivers in the world, the region surrounding the Amazon is mostly sparsely populated and the river itself has no bridges across it at any point.
It's about 1,500 times as long as a Beetle (Volkswagen).
In other words, 5,642,000,000 microns is 1,383 times the length of a Beetle (Volkswagen), and the length of a Beetle (Volkswagen) is 0.0007231 times that amount.(1964 model) (a.k.a. Volkswagen 1200, a.k.a. Käfer)
