It's about 0.000000002 times as long as The Indianapolis Motor Speedway
In other words, 0.0000390 shaftments is 0.00000000147727 times the length of The Indianapolis Motor Speedway, and the length of The Indianapolis Motor Speedway is 676,924,000 times that amount.(Speedway, Indiana) (rectangular oval course)
The rectangular oval course of the Indianapolis Motor Speedway is 26,400 shaftments. 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 0.000000002 times as long as Daytona International Speedway
In other words, 0.0000390 shaftments is 0.00000000147727 times the length of Daytona International Speedway, and the length of Daytona International Speedway is 676,924,000 times that amount.(Daytona Beach, Florida) (tri-oval course)
The tri-oval course of the Daytona International Speedway, upon which the NASCAR Daytona 500 is run, is 26,400 shaftments 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.
