It's about four-fifths as tall as Mount Everest
In other words, 6.920 kilometers is 0.782022 times the height of Mount Everest, and the height of Mount Everest is 1.27874 times that amount.(a.k.a. Mount Chomolungma, a.k.a. Sagarmatha, a.k.a. Mount Qomolangma, 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 rises 8.848860 kilometers above sea level at its summit. The plate tectonics of the Indian subcontinent continuously alter the mountain's peak â€” raising it by 0.00000400 kilometers and shifting it to the northeast by 0.00000450 kilometers each year.
It's about three-fourths as tall as a Mauna Loa
In other words, 6.920 kilometers is 0.7548 times the height of a Mauna Loa, and the height of a Mauna Loa is 1.325 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 9.20 kilometers 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 one-and-two-fifths times as tall as a Vinson Massif
In other words, 6.920 kilometers is 1.415 times the height of a Vinson Massif, and the height of a Vinson Massif is 0.7067 times that amount.(a.k.a. Mount Vinson) (Antarctica)
Mount Vinson, the highest peak of the Vinson Massif mountain, reaches 4.8920 kilometers at its peak. The mountain is named after Georgia Congressman Carl Vinson who emphatically promoted Antarctic exploration in the 1930s.
It's about one-and-two-fifths times as tall as a Puncak Jaya
In other words, 6.920 kilometers is 1.417 times the height of a Puncak Jaya, and the height of a Puncak Jaya is 0.7057 times that amount.(a.k.a. Mt. Carstensz, a.k.a. Carstensz Pyramid, a.k.a. Nemangkawi, a.k.a. Carstensz Toppen, a.k.a. Gunung Sukarno) (Papua province, Indonesia)
The highest point in Oceania (and therefore one of the seven summits) peak of Puncak Jaya is 4.8840 kilometers. Dutch explorer Jan Carstenszoon, the mountain's namesake, is said to have been ridiculed for claiming to have seen snow near the equator when he reported his discovery of the peak in 1623.
It's about two-thirds as deep as The Challenger Deep (Marianas Trench)
In other words, 6.920 kilometers is 0.63475 times the depth of The Challenger Deep (Marianas Trench), and the depth of The Challenger Deep (Marianas Trench) is 1.5754 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 km below sea level. The first manned expedition to the bottom of Challenger Deep took 4 hours and 48 minutes in 1960. This was the only manned descent to the floor of the Trench until 2012, when director James Cameron made the trip; several other descents have been made since then.
It's about three-fifths as tall as Maxwell Montes
In other words, 6.920 kilometers is 0.63 times the height of Maxwell Montes, and the height of Maxwell Montes is 1.6 times that amount.(Ishtar Terra, Venus)
Maxwell Montes rises to a total height of 11 km. 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 one-and-seven-tenths times as long as The Indianapolis Motor Speedway
In other words, 6.920 kilometers is 1.71996 times the length of The Indianapolis Motor Speedway, and the length of The Indianapolis Motor Speedway is 0.581409 times that amount.(Speedway, Indiana) (rectangular oval course)
The rectangular oval course of the Indianapolis Motor Speedway is 4.02336 km. While famous for its automotive racing, the first motorsport held at the track was a series of motorcycle races in August, 1909 — a little less than two years before the inaugural Indianapolis 500 race was run.
