Sort Order:
Closest first | Highest first | Lowest first

It's about one-five-hundred-thousandth as fast as The Speed of Light.
In other words, 630.2 yards per second is 0.00000192217938 times the speed of The Speed of Light, and the speed of The Speed of Light is 520,242.809 times that amount.
(C) (in a vacuum)
The speed of light (and all other electromagnetic radiation) in a perfect vacuum is known as "c" and measures exactly 327,857,019 yards per second, per the formal definition of the meter. While visible light travels close to this speed in air, it slows to 218,571,346 yards per second when passing through the glass of a typical window.
It's about one-one-hundred-fiftieth as fast as a bolt of Lightning.
In other words, the speed of a bolt of Lightning is 170 times 630.2 yards per second.
(atmospheric electrical discharge)
It's about one-seventieth as fast as a Meteor.
In other words, the speed of a Meteor is 71 times 630.2 yards per second.
(formally Meteoroid or meteorite, depending on the context; a.k.a. "shooting star", a.k.a. "falling star")

In other words, 630.2 yards per second is 0.074417 times the speed of The Space Shuttle, and the speed of The Space Shuttle is 13.438 times that amount.
(Orbiter vehicle velocity)
It's about three-fifths as fast as a Bullet (Rifle).
In other words, 630.2 yards per second is 0.63 times the speed of a Bullet (Rifle), and the speed of a Bullet (Rifle) is 1.59 times that amount.
(5.56 x 45 mm, a.k.a. 5.56 NATO)
It's about nine-tenths as fast as a Jet Fighter.
In other words, 630.2 yards per second is 0.86 times the speed of a Jet Fighter, and the speed of a Jet Fighter is 1.2 times that amount.
(for Lockheed Martin F-16, a.k.a. Fighting Falcon, a.k.a. Viper) (maximum speed at altitude)
It's about one-and-a-half times as fast as a Bullet (Handgun).
In other words, the speed of a Bullet (Handgun) is 0.667 times 630.2 yards per second.
