How fast is 442 miles per second?

Sort Order:
Closest first | Highest first | Lowest first

It's about seven-and-a-half times as fast as a bolt of Lightning.
In other words, the speed of a bolt of Lightning is 0.14 times 442 miles per second.
(atmospheric electrical discharge)
It's about seventeen times as fast as a Meteor.
In other words, the speed of a Meteor is 0.059 times 442 miles per second.
(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 6.9 miles per second and 45 miles per second, depending on their size. The fireball effect, known as ablation, ceases once the atmosphere has slowed the meteoroid to a velocity of about 1.7 miles per second.
It's about 90 times as fast as The Space Shuttle.
In other words, 442 miles per second is 91.86 times the speed of The Space Shuttle, and the speed of The Space Shuttle is 0.010886 times that amount.
(Orbiter vehicle velocity)
It's about one-four-hundredth as fast as The Speed of Light.
In other words, 442 miles per second is 0.00237274164 times the speed of The Speed of Light, and the speed of The Speed of Light is 421.453387 times that amount.
(C) (in a vacuum)
It's about 800 times as fast as a Bullet (Rifle).
In other words, 442 miles per second is 777 times the speed of a Bullet (Rifle), and the speed of a Bullet (Rifle) is 0.00129 times that amount.
(5.56 x 45 mm, a.k.a. 5.56 NATO)
It's about 1,000 times as fast as a Jet Fighter.
In other words, 442 miles per second is 1,100 times the speed of a Jet Fighter, and the speed of a Jet Fighter is 0.00091 times that amount.
(for Lockheed Martin F-16, a.k.a. Fighting Falcon, a.k.a. Viper) (maximum speed at altitude)
An F-16's maximum speed at altitude is approximately 0.41 miles per second. The F-16 has a flight ceiling of approximately 15 km (9.32 mi).
It's about 2,000 times as fast as a Bullet (Handgun).
In other words, 442 miles per second is 1,850 times the speed of a Bullet (Handgun), and the speed of a Bullet (Handgun) is 0.000541 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 0.238 miles per second. This type of ammunition has been the standard issue round of the United States Federal Bureau of Investigation (FBI) since 1990.
