Sort Order:
Closest first | Highest first | Lowest first

It's about one-fifth as fast as a Curveball (baseball)
In other words, 27.280 kilometers per hour is 0.220 times the speed of a Curveball (baseball), and the speed of a Curveball (baseball) is 4.50 times that amount.
(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 one-fifth as fast as a Fastball (baseball)
In other words, 27.280 kilometers per hour is 0.180 times the speed of a Fastball (baseball), and the speed of a Fastball (baseball) is 5.60 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 six times as fast as Walking Pedestrians (in Manhattan)
In other words, 27.280 kilometers per hour is 5.80 times the speed of Walking Pedestrians (in Manhattan), and the speed of Walking Pedestrians (in Manhattan) is 0.170 times that amount.
(Manhattan; average speed; 8,978 person-sample)
A 2006 Study by the New York City Department of City Planning found that pedestrians in that city walk at an average rate of 4.70 kilometers per hour. Pedestrians wearing headphones, the study went on to find, walk at a slightly faster 5.10 kilometers per hour
It's about one-tenth as fast as a Skydiver (belly-to-earth)
In other words, 27.280 kilometers per hour is 0.140 times the speed of a Skydiver (belly-to-earth), and the speed of a Skydiver (belly-to-earth) is 7.10 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 one-tenth as fast as a Tornado
In other words, 27.280 kilometers per hour is 0.13725510 times the speed of a Tornado, and the speed of a Tornado is 7.2857040 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.
It's about one-tenth as fast as a Skydiver (headfirst)
In other words, 27.280 kilometers per hour is 0.110 times the speed of a Skydiver (headfirst), and the speed of a Skydiver (headfirst) is 9.10 times that amount.
(Head-to-Earth orientation or standing, average conditions, terminal velocity)
A head-to-Earth or standing-oriented skydiver's terminal velocity assuming average conditions is about 260 kph. In a typical jump from 3,900 m (13,000 ft), a diver in this orientation will be in freefall for 46 seconds.
It's about one-tenth as fast as a Helicopter
In other words, the speed of a Helicopter is 10.40 times 27.280 kilometers per hour.
(for AH-64A Apache, a.k.a. Hughes Model 77) (maximum cruise speed)
The AH-64 helicopter, one of the primary helicopters used by the United States Army, flies at a top cruise speed of 284 kph. The AH-64 is the primary military helicopter of several nations including the United States, the United Kingdom, Israel, Japan, and the Netherlands.
