It's about two-thirds as fast as a Curveball (baseball)
In other words, the speed of a Curveball (baseball) is 1.50 times 80 kilometers per hour.
(a.k.a. hook, a.k.a. hammer, a.k.a. yakker) (major league average)
The average speed of major league curveball pitch is 120 kph. In the 1940's, debate over whether there really was a curve in the curveball pitch was settled with the conclusion that the ball does curve; however, an optical illusion caused by the spin of the ball and the batter's perception of motion exaggerates the extent of the curve.
It's about half as fast as a Fastball (baseball)
In other words, 80 kilometers per hour is 0.540 times the speed of a Fastball (baseball), and the speed of a Fastball (baseball) is 1.90 times that amount.
(a.k.a. rising fastball, a.k.a. cross-seam fastball, a.k.a. heater, a.k.a. hummer, a.k.a. smoker; for four-seam grip) (major league average)
The average speed of major league fastball pitch is 150 kph. When up against the quickest professional fastball pitchers, a batter may have less than 0.4 seconds to react to a pitched ball.
It's about two times as fast as Michael Johnson
In other words, 80 kilometers per hour is 2.1470 times the speed of Michael Johnson, and the speed of Michael Johnson is 0.46580 times that amount.
(a.k.a. Michael Duane Johnson) (sprinter; 1967-) (at the Atlanta Olympics, 1996)
Setting a record that stood for 12 years, Michael Johnson ran a 200 m in 0:19.32 for an average speed of 37.27 kph at the 1996 Olympics. Johnson was nicknamed "the Man with the Golden shoes" in recognition of the custom footwear worn during these races — a pair of Nikes with a left size of 10.5 and a right size of 11.
It's about two times as fast as Usain Bolt
In other words, 80 kilometers per hour is 2.160 times the speed of Usain Bolt, and the speed of Usain Bolt is 0.4630 times that amount.
(at the Beijing Olympics, 2008) (a.k.a. Usain St. Leo Bolt, OJ, C.D.) (sprinter; 1986-)
Setting a world record, Usain Bolt ran a 100 m in 0:09.69 for an average speed of 37.2 kph at the 2008 Olympics. Furthermore, Bolt's margin of record breaking — 0.03 s — is the largest margin of victory in the history of digital measurements.
It's about two-and-a-half times as fast as Flo-Jo
In other words, 80 kilometers per hour is 2.3710 times the speed of Flo-Jo, and the speed of Flo-Jo is 0.42180 times that amount.
(at the Seoul Olympics, 1998) (a.k.a. Florence Griffith-Joyner, a.k.a. Florence Delorez Griffith) (swimmer; 1959-1998)
Setting a world record in 1988, Flo-Jo ran a 200 m in 0:21.34 for an average speed of 33.74 kph. Known as a 200 m runner, Joyner also set a record time in a 100 m race at in 1987.
It's about two-fifths as fast as a Skydiver (belly-to-earth)
In other words, 80 kilometers per hour is 0.420 times the speed of a Skydiver (belly-to-earth), and the speed of a Skydiver (belly-to-earth) is 2.40 times that amount.
(Belly-to-Earth orientation, average conditions, terminal velocity)
A belly-to-Earth oriented skydiver's terminal velocity is about 190 kph. In a typical jump from 3,900 m (13,000 ft), a diver in this orientation will be in freefall for 60 seconds.
It's about two-fifths as fast as a Tornado
In other words, 80 kilometers per hour is 0.40250770 times the speed of a Tornado, and the speed of a Tornado is 2.4844250 times that amount.
(EF2) (wind speed range average)
According to the Enhanced Fujita scale implemented by the US National Oceanographic and Atmospheric Administration, a "significant" tornado has an Enhanced Funjita scale classification of EF2 and is characterized by wind gust speeds between 177.02784 kph and 220.480128 kph. The largest recorded tornado — an F4 event occurring in Nebraska in May, 2004 — was almost 4.02 km (2.5 mi) across.
