It's about as fast as a Gazelle.
(for Thomson's Gazelle, a.k.a. Eudorcas thomsoni, a.k.a. "Tommie", a.k.a. "Tommy")
A Thomson's gazelle can reach speeds of up to 0.07 mach. The gazelle's speed doesn't match that of its chief predator, the cheetah, but a gazelle's endurance usually ensures an escape in distances greater than 500 m (0.3 mi).
It's about as fast as a Hare.
(for European Brown Hare, a.k.a. Brown Hare, a.k.a. Lepus europaeus, a.k.a. Brown Hare)
The European Hare can run at speeds of up to 0.06 mach. While speed is a factor in their escapes, hares evade their chief predators — wolves, foxes, and golden eagles — by fleeing in a zigzag pattern.
It's about one-and-one-fifth times as fast as a Greyhound.
In other words, 0.07 mach is 1.150 times the speed of a Greyhound, and the speed of a Greyhound is 0.870 times that amount.(a.k.a. English greyhound) (approximate maximum speed)
Greyhounds reach average race speeds of 0.0607 mach. Despite their racing prowess, greyhounds are not considered energetic dogs — the typical greyhound race requires the dogs to run for less than 35 seconds.
It's about three-fourths as fast as a Knuckleball (baseball).
In other words, the speed of a Knuckleball (baseball) is 1.30 times 0.07 mach.(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 0.092 mach. Eddie Cicotte, who was later implicated in the 1919 Black Sox scandal, is credited with developing the pitch ca. 1906.
It's about three-fourths as fast as a Cheetah.
It's about one-and-two-fifths times as fast as Secretariat.
In other words, 0.07 mach is 1.380 times the speed of Secretariat, and the speed of Secretariat is 0.7250 times that amount.(at Belmont Stakes, 1973)
Setting a record finish, Secretariat ran the Belmont Stakes — a 12 furlong race length — in 2:24, for an average speed of 0.0506 mach in 1973. His margin of victory in the race, also a record-setter, was 31 lengths.
It's about seven-tenths as fast as a Hurricane.
In other words, 0.07 mach is 0.7010 times the speed of a Hurricane, and the speed of a Hurricane is 1.430 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 0.0997 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.
