It's about as fast as a bolt of Lightning.
(atmospheric electrical discharge)
A bolt of lightning can travel at up to 190,000 knots when arcing from the atmosphere to the Earth. An estimated 280 million lightning strikes strikes occur each year.
It's about two-and-a-half times as fast as a Meteor.
In other words, the speed of a Meteor is 0.430 times 190,000 knots.(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 22,000 knots and 140,000 knots, depending on their size. The fireball effect, known as ablation, ceases once the atmosphere has slowed the meteoroid to a velocity of about 5,400 knots.
It's about twelve-and-a-half times as fast as The Space Shuttle.
In other words, 190,000 knots is 12.6230 times the speed of The Space Shuttle, and the speed of The Space Shuttle is 0.07922 times that amount.(Orbiter vehicle velocity)
The space shuttle orbits at a speed of 15,052 knots. 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 100 times as fast as a Bullet (Rifle).
In other words, 190,000 knots is 107 times the speed of a Bullet (Rifle), and the speed of a Bullet (Rifle) is 0.00935 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 1,780 knots. 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 150 times as fast as a Jet Fighter.
It's about 250 times as fast as a Bullet (Handgun).
In other words, 190,000 knots is 255 times the speed of a Bullet (Handgun), and the speed of a Bullet (Handgun) is 0.00392 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 745 knots. This type of ammunition has been the standard issue round of the United States Federal Bureau of Investigation (FBI) since 1990.
It's about 300 times as fast as The Speed of Sound.
In other words, 190,000 knots is 285 times the speed of The Speed of Sound, and the speed of The Speed of Sound is 0.00351 times that amount.(in dry air at 20°C)
The speed of sound in dry air at 20°C (68°F) is 667 knots. Air is a relatively poor acoustic conductor, however, as sound will travel at speeds of between 2,910 knots to 3,030 knots in water, depending on its salinity.
