How fast is 68 times the speed of light?

Sort Order:
Closest first | Highest first | Lowest first

It's about 250,000,000 times as fast as a Helicopter
In other words, 68 times the speed of light is 258,000,000 times the speed of a Helicopter, and the speed of a Helicopter is 0.00000000388 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 0.0000002630 times the speed of light. 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 300,000,000 times as fast as a Skydiver (headfirst)
In other words, 68 times the speed of light is 280,000,000 times the speed of a Skydiver (headfirst), and the speed of a Skydiver (headfirst) is 0.0000000036 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 0.000000240 times the speed of light. 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 350,000,000 times as fast as a Tornado
In other words, 68 times the speed of light is 369,246,400 times the speed of a Tornado, and the speed of a Tornado is 0.000000002708219 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 0.00000016402810 times the speed of light and 0.00000020428960 times the speed of light. 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 400,000,000 times as fast as a Skydiver (belly-to-earth)
In other words, 68 times the speed of light is 380,000,000 times the speed of a Skydiver (belly-to-earth), and the speed of a Skydiver (belly-to-earth) is 0.0000000026 times that amount.
(Belly-to-Earth orientation, average conditions, terminal velocity)
A belly-to-Earth oriented skydiver's terminal velocity is about 0.000000180 times the speed of light. 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 500,000,000 times as fast as a Fastball (baseball)
In other words, 68 times the speed of light is 500,000,000 times the speed of a Fastball (baseball), and the speed of a Fastball (baseball) is 0.0000000020 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 0.000000140 times the speed of light. 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 600,000,000 times as fast as a Curveball (baseball)
In other words, 68 times the speed of light is 600,000,000 times the speed of a Curveball (baseball), and the speed of a Curveball (baseball) is 0.0000000017 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 0.000000110 times the speed of light. 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 600,000,000 times as fast as a Hurricane
In other words, 68 times the speed of light is 616,000,000 times the speed of a Hurricane, and the speed of a Hurricane is 0.00000000162 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 0.000000110 times the speed of light. 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 0.0000002870 times the speed of light.
