It's about one-five-hundred-fiftieth as fast as a Knuckleball (baseball).
In other words, the speed of a Knuckleball (baseball) is 560 times 128 inches per minute.
(a.k.a. knuckler, a.k.a. floater, a.k.a. dancer, a.k.a. butterfly ball) (major league average)
The average speed of major league knuckleball pitch is 72,000 inches per minute. Eddie Cicotte, who was later implicated in the 1919 Black Sox scandal, is credited with developing the pitch ca. 1906.
It's about one-five-hundred-fiftieth as fast as a Cheetah.
In other words, 128 inches per minute is 0.001766 times the speed of a Cheetah, and the speed of a Cheetah is 566.30 times that amount.
(Acinonyx jubatus)
The cheetah can reach speeds of up to 72,510 inches per minute in short bursts. From a crouching position, the cheetah can attain these speeds in just 2.25 seconds.
It's about one-six-hundredth as fast as a Hurricane.
In other words, 128 inches per minute is 0.00164 times the speed of a Hurricane, and the speed of a Hurricane is 610 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 78,100 inches per minute. 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 203,000 inches per minute.
It's about one-six-hundred-fiftieth as fast as a Curveball (baseball).
In other words, the speed of a Curveball (baseball) is 630 times 128 inches per minute.
(a.k.a. hook, a.k.a. hammer, a.k.a. yakker) (major league average)
The average speed of major league curveball pitch is 79,000 inches per minute. 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-seven-hundred-fiftieth as fast as a Fastball (baseball).
In other words, the speed of a Fastball (baseball) is 770 times 128 inches per minute.
(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 98,000 inches per minute. 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-one-thousandth as fast as a Skydiver (belly-to-earth).
In other words, the speed of a Skydiver (belly-to-earth) is 1,000 times 128 inches per minute.
(Belly-to-Earth orientation, average conditions, terminal velocity)
A belly-to-Earth oriented skydiver's terminal velocity is about 120,000 inches per minute. 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-thousandth as fast as a Tornado.
In other words, 128 inches per minute is 0.0009814747 times the speed of a Tornado, and the speed of a Tornado is 1,018.8750 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 116,160 inches per minute and 144,672 inches per minute. The largest recorded tornado — an F4 event occurring in Nebraska in May, 2004 — was almost 4.02 km (2.5 mi) across.
