It's about one-one-hundredth as tall as a Mauna Loa.
In other words, 500 shaftments is 0.008312 times the height of a Mauna Loa, and the height of a Mauna Loa is 120.30 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 60,370 shaftments 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-one-hundred-fiftieth as tall as The Challenger Deep (Marianas Trench).
In other words, 500 shaftments is 0.0069895 times the height of The Challenger Deep (Marianas Trench), and the height of The Challenger Deep (Marianas Trench) is 143.07 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 71,535 shaftments 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-one-hundred-fiftieth as tall as Maxwell Montes.
In other words, the height of Maxwell Montes is 140 times 500 shaftments.(Ishtar Terra, Venus)
Maxwell Montes rises to a total height of 72,000 shaftments. 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 200 times as tall as a Bowling Pin.
In other words, the height of a Bowling Pin is 0.005 times 500 shaftments.(USBC specifications; tenpin)
According to the United States Bowling Congress specifications, a tenpin bowling pin should be within 0.00521 shaftments of 2.50 shaftments 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-hundred-fiftieth as tall as Olympus Mons.
In other words, the height of Olympus Mons is 360 times 500 shaftments.(a.k.a. Mount Olympus) (Mars)
The tallest mountain in the solar system, Olympus Mons rises to approximately 180,000 shaftments. 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, 500 shaftments is 0.00087 times the length of The Panama Canal, and the length of The Panama Canal is 1,100 times that amount.(Canal de Panamá) (Panama)
Connecting the Atlantic and Pacific Oceans across the Isthmus of Panama, the Canal measures 580,000 shaftments in length. Ships passing through the Canal are raised (and then lowered) 170 shaftments above sea level through the lock-and-dam system.
It's about 1,500 times as tall as a Golf Tee.
In other words, the height of a Golf Tee is 0.00071 times 500 shaftments.The most common golf tee size and the length preferred for iron and most wood clubs is 0.350 shaftments tall. The tee did not come into common use until it was promoted by professional golfers Walter Hagen and Joe Kirkwood, as part of a marketing effort by the patent-holder of the well-known, "Reddy Tee."
