How fast is 630.2 yards per second?
It's about one-and-two-thirds times as fast as The Speed of Sound
The speed of The Speed of Sound is about 375 yards per second.
(in dry air at 20°C)
The speed of sound in dry air at 20°C (68°F) is 375 yards per second. Air is a relatively poor acoustic conductor, however, as sound will travel at speeds of between 1,640 yards per second to 1,710 yards per second in water, depending on its salinity.
It's about one-and-a-half times as fast as a Bullet (Handgun)
The speed of a Bullet (Handgun) is about 420 yards per second.
(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 419 yards per second. This type of ammunition has been the standard issue round of the United States Federal Bureau of Investigation (FBI) since 1990.
It's about nine-tenths as fast as a Jet Fighter
The speed of a Jet Fighter is about 730 yards per second.
(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 730 yards per second. The F-16 has a flight ceiling of approximately 15 km (9.32 mi).
It's about three-fifths as fast as a Bullet (Rifle)
The speed of a Bullet (Rifle) is about 1,000 yards per second.
(5.56 x 45 mm, a.k.a. 5.56 NATO)
A 5.56 x 45 mm cartridge is fired at a velocity of 1,000 yards per second. 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 one-fifteenth as fast as The Space Shuttle
The speed of The Space Shuttle is about 8,468.50 yards per second.
(Orbiter vehicle velocity)
The space shuttle orbits at a speed of 8,468.50 yards per second. 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 one-seventieth as fast as a Meteor
The speed of a Meteor is about 46,000 yards 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 12,000 yards per second and 79,000 yards 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 3,000 yards per second.
It's about one-one-hundred-fiftieth as fast as a bolt of Lightning
The speed of a bolt of Lightning is about 110,000 yards per second.
(atmospheric electrical discharge)
A bolt of lightning can travel at up to 110,000 yards per second when arcing from the atmosphere to the Earth. An estimated 280 million lightning strikes strikes occur each year.
It's about one-five-hundred-thousandth as fast as The Speed of Light
The speed of The Speed of Light is about 327,857,018.810150 yards per second.
(C) (in a vacuum)
The speed of light (and all other electromagnetic radiation) in a perfect vacuum is known as "c" and measures 327,857,018.810150 yards per second, per the formal definition of the meter. While visible light travels close to this speed in air, it slows to 218,571,345.877080 yards per second when passing through the glass of a typical window.
