It's about three-fifths as long as The Indianapolis Motor Speedway.
In other words, the length of The Indianapolis Motor Speedway is 1.666670 times 12 furlongs.(Speedway, Indiana) (rectangular oval course)
The rectangular oval course of the Indianapolis Motor Speedway is 20 furlongs. While famous for its automotive racing, the first motorsport held at the track was a series of motorcycle races in August, 1909 — a little less than two years before the inaugural Indianapolis 500 race was run.
It's about three-fifths as long as Daytona International Speedway.
In other words, the length of Daytona International Speedway is 1.666670 times 12 furlongs.(Daytona Beach, Florida) (tri-oval course)
The tri-oval course of the Daytona International Speedway, upon which the NASCAR Daytona 500 is run, is 20 furlongs in length. Although the tri-oval design is said to allow for greater visibility during the race, the real reason for the then-unique design was that plot available for construction of the track was only 350 acres and could not accommodate a traditional oval layout of appropriate length.
It's about half as tall as a Puncak Jaya.
In other words, 12 furlongs is 0.49430 times the height of a Puncak Jaya, and the height of a Puncak Jaya is 2.023 times that amount.(a.k.a. Mt. Carstensz, a.k.a. Carstensz Pyramid, a.k.a. Nemangkawi, a.k.a. Carstensz Toppen, a.k.a. Gunung Sukarno) (Papua province, Indonesia)
The highest point in Oceania (and therefore one of the seven summits) peak of Puncak Jaya is 24.280 furlongs. Dutch explorer Jan Carstenszoon, the mountain's namesake, is said to have been ridiculed for claiming to have seen snow near the equator when he reported his discovery of the peak in 1623.
It's about half as tall as a Vinson Massif.
In other words, 12 furlongs is 0.49350 times the height of a Vinson Massif, and the height of a Vinson Massif is 2.026 times that amount.(a.k.a. Mount Vinson) (Antarctica)
Mount Vinson, the highest peak of the Vinson Massif mountain, reaches 24.320 furlongs at its peak. The mountain is named after Georgia Congressman Carl Vinson who emphatically promoted Antarctic exploration in the 1930s.
It's about two-fifths as tall as Mount Elbrus.
In other words, 12 furlongs is 0.42790 times the height of Mount Elbrus, and the height of Mount Elbrus is 2.3370 times that amount.(a.k.a. Mingi Tau, a.k.a. Эльбрус, a.k.a. იალბუზი) (Karachay-Cherkessia and Kabardino-Balkaria, Russia) (west summit)
The west summit of the dual-summit volcano Mount Elbrus is 28.05 furlongs at its peak and is the highest peak in both Russia and the European continent. Until 1976, a cable car would take visitors to the mountain as far up as the Garabashi camp, located at an elevation of 18.890 furlongs.
It's about two-fifths as tall as a Kilimanjaro.
In other words, 12 furlongs is 0.4097950 times the height of a Kilimanjaro, and the height of a Kilimanjaro is 2.440240 times that amount.(a.k.a. Mount Kilimanjaro) (Tanzania) (to Uhuru peak; 2008 gravimeter measurement)
Kilimanjaro rises to 29.28290 furlongs at its peak. An isolated peak with no surrounding mountain range, Kilimanjaro is considered the world's tallest freestanding mountain.
It's about two-fifths as tall as Mount Logan.
In other words, 12 furlongs is 0.40510 times the height of Mount Logan, and the height of Mount Logan is 2.4690 times that amount.(Kluane National Park and Reserve, Yukon, Canada) (elevation)
The highest mountain in Canada, Mount Logan has a total height of 29.630 furlongs. The high altitude and northern latitude of the mountain resulted in one-time temperature of -77.5 °C — the lowest temperature ever recorded outside of Antarctica.
