It's about twenty times as fast as a Sloth.
In other words, the speed of a Sloth is 0.048 times 0.0043 mach.(for Brown-throated three-toed sloth, Bradypus variegatus)
The three-toed sloth moves along the ground at an average speed of 0.0002 mach. Long thought to be lengthy sleepers, a 2008 study concluded that sloths sleep an average of only 9.6 hours per day.
It's about one-twentieth as fast as a Cheetah.
It's about one-twenty-fifth as fast as a Hurricane.
In other words, the speed of a Hurricane is 23.20 times 0.0043 mach.(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 0.0997 mach. 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 0.260 mach.
It's about one-twenty-fifth as fast as a Curveball (baseball).
In other words, the speed of a Curveball (baseball) is 24 times 0.0043 mach.(a.k.a. hook, a.k.a. hammer, a.k.a. yakker) (major league average)
The average speed of major league curveball pitch is 0.10 mach. 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-thirtieth as fast as a Fastball (baseball).
In other words, the speed of a Fastball (baseball) is 29 times 0.0043 mach.(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 0.130 mach. 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-thirty-fifth as fast as a Skydiver (belly-to-earth).
In other words, the speed of a Skydiver (belly-to-earth) is 37 times 0.0043 mach.(Belly-to-Earth orientation, average conditions, terminal velocity)
A belly-to-Earth oriented skydiver's terminal velocity is about 0.160 mach. 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-fortieth as fast as a Tornado.
In other words, 0.0043 mach is 0.02582311 times the speed of a Tornado, and the speed of a Tornado is 38.7250 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 0.14831520 mach and 0.18471980 mach. The largest recorded tornado — an F4 event occurring in Nebraska in May, 2004 — was almost 4.02 km (2.5 mi) across.
