Sort Order:
Closest first | Highest first | Lowest first

 It's about one-thirtieth as fast as a Helicopter. In other words, 272.50 centimeters per second is 0.0345 times the speed of a Helicopter, and the speed of a Helicopter is 29 times that amount. (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 7,890 centimeters per second. The AH-64 is the primary military helicopter of several nations including the United States, the United Kingdom, Israel, Japan, and the Netherlands. It's about one-twenty-fifth as fast as a Skydiver (headfirst). In other words, the speed of a Skydiver (headfirst) is 26 times 272.50 centimeters per second. (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 7,200 centimeters per second. 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-twentieth as fast as a Tornado. In other words, 272.50 centimeters per second is 0.0493575 times the speed of a Tornado, and the speed of a Tornado is 20.260350 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 4,917.440 centimeters per second and 6,124.4480 centimeters per second. 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-twentieth as fast as a Skydiver (belly-to-earth). In other words, the speed of a Skydiver (belly-to-earth) is 20 times 272.50 centimeters per second. (Belly-to-Earth orientation, average conditions, terminal velocity)A belly-to-Earth oriented skydiver's terminal velocity is about 5,300 centimeters per second. 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-fifteenth as fast as a Fastball (baseball). In other words, the speed of a Fastball (baseball) is 15 times 272.50 centimeters per second. (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 4,200 centimeters per second. 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 one-fifteenth as fast as a Curveball (baseball). In other words, the speed of a Curveball (baseball) is 13 times 272.50 centimeters per second. (a.k.a. hook, a.k.a. hammer, a.k.a. yakker) (major league average)The average speed of major league curveball pitch is 3,300 centimeters per second. 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-tenth as fast as a Hurricane. In other words, 272.50 centimeters per second is 0.0823 times the speed of a Hurricane, and the speed of a Hurricane is 12.20 times that amount. (formally: Topical cyclone; a.k.a. typhoon)A hurricane is defined by the US National Hurricane Center as a Northern Hemisphere tropical storm having one-minute average wind-speeds of at least 3,310 centimeters per second. Typhoons Tip (October, 1979) and Keith (October, 1997) and Hurricanes Camille (August, 1969) and Allen (August, 1980) jointly hold the record for highest tropical storm wind speeds at 8,610 centimeters per second.
