It's about one-one-hundredth as tall as The Challenger Deep (Marianas Trench).
In other words, 1.250 leas is 0.0083875 times the height of The Challenger Deep (Marianas Trench), and the height of The Challenger Deep (Marianas Trench) is 119.230 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 149.03 leas 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 100 times as long as a Man's Footstep.
In other words, 1.250 leas is 120 times the length of a Man's Footstep, and the length of a Man's Footstep is 0.0083 times that amount.(for healthy, middle-aged man of average height; single step length)
According to studies by The University of Oklahoma's Health Sciences Center, the average length of a man's step is 0.011 leas, for an average stride (two-step's length) of 0.021 leas. The average person walks at a speed of about 1.3 m/s
It's about one-one-hundredth as tall as Maxwell Montes.
In other words, 1.250 leas is 0.0083 times the height of Maxwell Montes, and the height of Maxwell Montes is 120 times that amount.(Ishtar Terra, Venus)
Maxwell Montes rises to a total height of 150 leas. 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 150 times as long as a Woman's Footstep.
In other words, the length of a Woman's Footstep is 0.0071 times 1.250 leas.(for healthy, middle-aged woman of average height; single step length)
According to studies by The University of Oklahoma's Health Sciences Center, the average length of a woman's step is 0.009 leas, for an average stride (two-step's length) of 0.018 leas. The average person walks at a speed of about 1.3 m/s
It's about 250 times as tall as a Bowling Pin.
In other words, the height of a Bowling Pin is 0.00417 times 1.250 leas.(USBC specifications; tenpin)
According to the United States Bowling Congress specifications, a tenpin bowling pin should be within 0.00001090 leas of 0.00521 leas in height. The USBC further mandates that certified pins be made of sugar maple wood, unless otherwise approved by the organization.
It's about one-three-hundredth as tall as Olympus Mons.
In other words, 1.250 leas is 0.0034 times the height of Olympus Mons, and the height of Olympus Mons is 290 times that amount.(a.k.a. Mount Olympus) (Mars)
The tallest mountain in the solar system, Olympus Mons rises to approximately 370 leas. 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-one-thousandth as long as The Panama Canal.
In other words, the length of The Panama Canal is 1,000 times 1.250 leas.(Canal de Panamá) (Panama)
Connecting the Atlantic and Pacific Oceans across the Isthmus of Panama, the Canal measures 1,200 leas in length. Ships passing through the Canal are raised (and then lowered) 0.360 leas above sea level through the lock-and-dam system.
