Running from Irvine to San Fernando, The 405 runs a total of 20.9760 leagues. The 405 is the most heavily-trafficed freeway in the United States, with an average speed as low as 8 kph during rush hours.
It's about forty times as long as The English Channel.
In other words, the length of The English Channel is 0.0278 times 692.60 leagues.(average width between Isle of Ushant and The Walde Lighthouse) (La Manche, Ärmelkanal, Mor Breizh, Mor Bretannek) (a.k.a. The Channel)
The English Channel measures between 19.30 leagues, narrowing as it flows northeast. The world speed record for a Channel crossing by swimmer was set by Australian Trent Grimsey in 2012, with a time of 6 hours, 55 minutes.
It's about 45 times as long as The Panama Canal.
In other words, the length of The Panama Canal is 0.023 times 692.60 leagues.(Canal de Panamá) (Panama)
Connecting the Atlantic and Pacific Oceans across the Isthmus of Panama, the Canal measures 16 leagues in length. Ships passing through the Canal are raised (and then lowered) 0.0047 leagues above sea level through the lock-and-dam system.
It's about one-one-hundredth as long as The Distance from Earth to the Moon.
In other words, 692.60 leagues is 0.01000968 times the length of The Distance from Earth to the Moon, and the length of The Distance from Earth to the Moon is 99.903290 times that amount.(a.k.a. Luna) (median of semi-major axis, or apigee, and semi-minor axes, or perigee)
The orbit of the Moon around the Earth is elliptical, with an average distance of 69,193.03 leagues from center-to-center. About 428.376 kg of moon rock have been cataloged on the Earth, from the American Apollo and Soviet Luna Programs, and from samples that have been extracted from meteorites.
It's about 150 times as tall as Olympus Mons.
In other words, the height of Olympus Mons is 0.0071 times 692.60 leagues.(a.k.a. Mount Olympus) (Mars)
The tallest mountain in the solar system, Olympus Mons rises to approximately 4.90 leagues. 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 350 times as tall as Maxwell Montes.
In other words, the height of Maxwell Montes is 0.0029 times 692.60 leagues.(Ishtar Terra, Venus)
Maxwell Montes rises to a total height of 2 leagues. 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.
