It's about one-fifteenth as long as The Amazon River.
In other words, 446,000 meters is 0.06929 times the length of The Amazon River, and the length of The Amazon River is 14.430 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 meters. 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 seventeen times as tall as Olympus Mons.
In other words, the height of Olympus Mons is 0.059 times 446,000 meters.(a.k.a. Mount Olympus) (Mars)
The tallest mountain in the solar system, Olympus Mons rises to approximately 27,000 meters. The mountain has been known to astronomers since the nineteenth century because it is tall enough to rise above Mars' frequent dust storms.
It's about one-twentieth as long as The Great Wall of China (total).
In other words, 446,000 meters is 0.0504 times the length of The Great Wall of China (total), and the length of The Great Wall of China (total) is 19.80 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) (total length, all branches)
The Great Wall of China, including all branches and trenches, is 8,850,000 meters. 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 40 times as tall as The Challenger Deep (Marianas Trench).
In other words, 446,000 meters is 40.910 times the height of The Challenger Deep (Marianas Trench), and the height of The Challenger Deep (Marianas Trench) is 0.024444 times that amount.(near Marianas Islands, a.k.a. Ladrones Islands, northwestern Pacific Ocean) (depth below sea level)
The Challenger Deep, at the southern end of the Marianas Trench, reaches a depth of 10,902 meters below sea level. There has been only one manned expedition to the bottom of Challenger Deep — a 1960 voyage that took 4 hours and 48 minutes to reach the bottom.
It's about 40 times as tall as Maxwell Montes.
In other words, 446,000 meters is 41 times the height of Maxwell Montes, and the height of Maxwell Montes is 0.024 times that amount.(Ishtar Terra, Venus)
Maxwell Montes rises to a total height of 11,000 meters. Since Venus does not seem to have the kind of tectonic activity which gives rise to mountains on Earth, the origin of the Venusian mountain remains the subject of some dispute.
It's about 50 times as tall as a Mauna Loa.
In other words, 446,000 meters is 48.650 times the height of a Mauna Loa, and the height of a Mauna Loa is 0.02055 times that amount.(Hawaii) (Hawaiian island volcano) (total height from seafloor)
Mauna Loa, one of the five volcanoes which forms the island of Hawaii and the tallest mountain in total height in the world, rises to 9,168 m above the seafloor. The peak of Loa is home to the approximately 6,000 sq. m (0.6 ha) Lake Waiau, one of the highest altitude lakes in the United States outside of Colorado.
It's about 50 times as tall as Mount Everest.
In other words, 446,000 meters is 50.40 times the height of Mount Everest, and the height of Mount Everest is 0.0198 times that amount.(a.k.a. Mount Chomolungma, a.k.a. सगरमाथा, a.k.a. Chajamlungma, a.k.a. ཇོ་མོ་གླང་མ, a.k.a. 珠穆朗玛峰, a.k.a. Zhūmùlǎngmǎ Fēng) (Sagarmatha Zone, Nepal and Tibet, China) (to summit, excluding snow depth)
Mount Everest is 8,850 m above sea level at its summit. The plate tectonics of the Indian subcontinent continuously alter the mountain's peak — raising it by 0.004 meters and shifting it to the northeast by 0.0045 meters each year.
