It's about one-and-three-fifths times as fast as a bolt of Lightning.
In other words, the speed of a bolt of Lightning is 0.630 times 482 mach.(atmospheric electrical discharge)
A bolt of lightning can travel at up to 290 mach when arcing from the atmosphere to the Earth. An estimated 280 million lightning strikes strikes occur each year.
It's about four times as fast as a Meteor.
In other words, 482 mach is 3.80 times the speed of a Meteor, and the speed of a Meteor is 0.260 times that amount.(formally Meteoroid or meteorite, depending on the context; a.k.a. "shooting star", a.k.a. "falling star")
Small meteoroids enter the Earth's atmosphere at speeds between 34 mach and 220 mach, depending on their size. The fireball effect, known as ablation, ceases once the atmosphere has slowed the meteoroid to a velocity of about 8.40 mach.
It's about twenty-and-a-half times as fast as The Space Shuttle.
In other words, 482 mach is 20.6380 times the speed of The Space Shuttle, and the speed of The Space Shuttle is 0.048454 times that amount.(Orbiter vehicle velocity)
The space shuttle orbits at a speed of 23.3560 mach. During liftoff, the space shuttle accelerates to orbital speed in 8.5 minutes, consuming over 1.59 million kg (3.51 million lbs) of propellant in the process.
It's about 200 times as fast as a Bullet (Rifle).
In other words, 482 mach is 175 times the speed of a Bullet (Rifle), and the speed of a Bullet (Rifle) is 0.00571 times that amount.(5.56 x 45 mm, a.k.a. 5.56 NATO)
A 5.56 x 45 mm cartridge is fired at a velocity of 2.760 mach. As the NATO rifle cartridge, it is used by the military forces of more than thirty-one countries, including use in the M16 series, M4 Carbine, HK-416, and M249 Squad automatic weapons used by the United States armed forces.
It's about 250 times as fast as a Jet Fighter.
It's about 400 times as fast as a Bullet (Handgun).
In other words, 482 mach is 416 times the speed of a Bullet (Handgun), and the speed of a Bullet (Handgun) is 0.0024 times that amount.(for .40 Smith & Wesson 135 grain Sierra JHP, VV 3N37 powder, Fed. 100 primer, Remington case) (muzzle velocity)
A 0.40 caliber Smith & Wesson bullet has a muzzle a velocity of 1.160 mach. This type of ammunition has been the standard issue round of the United States Federal Bureau of Investigation (FBI) since 1990.
It's about 450 times as fast as The Speed of Sound.
In other words, 482 mach is 466 times the speed of The Speed of Sound, and the speed of The Speed of Sound is 0.00215 times that amount.(in dry air at 20°C)
The speed of sound in dry air at 20°C (68°F) is 1.03 mach. Air is a relatively poor acoustic conductor, however, as sound will travel at speeds of between 4.520 mach to 4.710 mach in water, depending on its salinity.
