It's about one-twentieth as tall as Mount Everest.
In other words, 0.4120 kilometers is 0.0466 times the height of Mount Everest, and the height of Mount Everest is 21.50 times that amount.(a.k.a. Mount Chomolungma, a.k.a. सगरमाथा, a.k.a.

Mount Everest is 8.850 kilometers above sea level at its summit. The plate tectonics of the Indian subcontinent continuously alter the mountain's peak — raising it by 0.00000400 kilometers and shifting it to the northeast by 0.00000450 kilometers each year.
It's about twenty times as long as a Bowling Lane.
In other words, 0.4120 kilometers is 21.5080 times the length of a Bowling Lane, and the length of a Bowling Lane is 0.046494 times that amount.(USBC specifications; tenpin; including pin deck)
According to the United States Bowling Congress specifications, a tenpin bowling lane should measure 0.019156 kilometers. In a Professional Bowling Association game, the lane must be lubricated by about 25 ml (0.85 fl. oz) of oil.
It's about one-twentieth as tall as a Mauna Loa.
In other words, 0.4120 kilometers is 0.04494 times the height of a Mauna Loa, and the height of a Mauna Loa is 22.250 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-twenty-fifth as tall as The Challenger Deep (Marianas Trench).
In other words, 0.4120 kilometers is 0.037791 times the height of The Challenger Deep (Marianas Trench), and the height of The Challenger Deep (Marianas Trench) is 26.4610 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. 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 thirty times as tall as The Hollywood Sign.
In other words, the height of The Hollywood Sign is 0.037 times 0.4120 kilometers.(a.k.a. Hollywoodland Sign) (Mount Lee, Hollywood Hills, Santa Monica Mountains, California)
Each of the white letters in the Hollywood Sign measures 0.015 kilometers tall. Built as an advertisement in 1923, the sign was intended to stand for only eighteen months.
It's about one-twenty-fifth as tall as Maxwell Montes.
In other words, the height of Maxwell Montes is 27 times 0.4120 kilometers.(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 thirty times as long as a Semitrailer.
In other words, 0.4120 kilometers is 28.160 times the length of a Semitrailer, and the length of a Semitrailer is 0.03551 times that amount.(a.k.a. semi-trailer truck, a.k.a. semi, a.k.a. tractor-trailer, a.k.a. truck and trailer, a.k.a. eighteen-wheeler, a.k.a. big rig, a.k.a.

According to the United States Department of Transportation (DOT), the maximum allowable length of a semitrailer pulled by a road tractor truck is 0.01463 kilometers (unless superseded by state law). These regulations also allow the vehicles to tow up to 36,000 kg in gross weight.
