It's about thirty times as long as a London bus.
In other words, 242.90 ells is 33.10 times the length of a London bus, and the length of a London bus is 0.0302 times that amount.(Routemaster Double-Decker, RM standard specification)
The Routemaster Double-Decker buses, well-known as icons of London, measure 7.330 ells 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.
It's about one-fortieth as tall as The Challenger Deep (Marianas Trench).
In other words, 242.90 ells is 0.025466 times the height of The Challenger Deep (Marianas Trench), and the height of The Challenger Deep (Marianas Trench) is 39.2680 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 9,538.10 ells 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 one-fortieth as tall as Maxwell Montes.
In other words, the height of Maxwell Montes is 40 times 242.90 ells.(Ishtar Terra, Venus)
Maxwell Montes rises to a total height of 9,600 ells. 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 Giraffe.
It's about 70 times as long as a Beetle (Volkswagen).
In other words, 242.90 ells is 68.06 times the length of a Beetle (Volkswagen), and the length of a Beetle (Volkswagen) is 0.01469 times that amount.(1964 model) (a.k.a. Volkswagen 1200, a.k.a. Käfer)
A 1964 Volkswagen Beetle measures 3.5690 ells. As the longest continuously-produced automobile design — in production for 75 years between 1938 and 2003 — the Beetle was voted the most fourth-most influential car of the twentieth century by the Global Automotive Elections Foundation.
It's about one-one-hundredth as tall as Olympus Mons.
In other words, the height of Olympus Mons is 100 times 242.90 ells.(a.k.a. Mount Olympus) (Mars)
The tallest mountain in the solar system, Olympus Mons rises to approximately 24,000 ells. 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 100 times as tall as a Christmas Tree (artificial).
In other words, 242.90 ells is 120 times the height of a Christmas Tree (artificial), and the height of a Christmas Tree (artificial) is 0.0083 times that amount.(artificial; average height)
The most common height of an artificial Christmas Tree is 2 ells. According to the most recent USDA Census of Agriculture, a total of 1,389.59 sq. km (343,374 acres) of Christmas Trees were farmed in the US in 2007.
To all those observing, Merry Christmas from The Measure of Things!
