Closest first | Highest first | Lowest first

It's about one-one-hundred-fiftieth as fast as a Helicopter
In other words, 2 kilometers per hour is 0.00704 times the speed of a Helicopter, and the speed of a Helicopter is 142 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 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.
It's about one-one-hundred-fiftieth as fast as a Skydiver (headfirst)
In other words, the speed of a Skydiver (headfirst) is 130 times 2 kilometers per hour.
(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-one-hundredth as fast as a Skydiver (belly-to-earth)
In other words, the speed of a Skydiver (belly-to-earth) is 100 times 2 kilometers per hour.
(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-one-hundredth as fast as a Tornado
In other words, 2 kilometers per hour is 0.01006269 times the speed of a Tornado, and the speed of a Tornado is 99.377010 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-seventieth as fast as a Fastball (baseball)
In other words, the speed of a Fastball (baseball) is 71 times 2 kilometers per hour.
(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 one-sixty-fifth as fast as a Curveball (baseball)
In other words, the speed of a Curveball (baseball) is 63 times 2 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 one-sixtieth as fast as a Hurricane
In other words, 2 kilometers per hour is 0.0168 times the speed of a Hurricane, and the speed of a Hurricane is 59.50 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 119 kph. 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 310 kph (192.63 mph).
