How fast is 478.7 kilometers per minute?
It's about twenty times as fast as The Speed of Sound
The speed of The Speed of Sound is about 20.60 kilometers per minute.
(in dry air at 20°C)
The speed of sound in dry air at 20°C (68°F) is 20.60 kilometers per minute. Air is a relatively poor acoustic conductor, however, as sound will travel at speeds of between 89.80 kilometers per minute to 93.60 kilometers per minute in water, depending on its salinity.
It's about 21 times as fast as a Bullet (Handgun)
The speed of a Bullet (Handgun) is about 23 kilometers per minute.
(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 23 kilometers per minute. This type of ammunition has been the standard issue round of the United States Federal Bureau of Investigation (FBI) since 1990.
It's about twelve times as fast as a Jet Fighter
The speed of a Jet Fighter is about 40 kilometers per minute.
(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 40 kilometers per minute. The F-16 has a flight ceiling of approximately 15 km (9.32 mi).
It's about eight-and-a-half times as fast as a Bullet (Rifle)
The speed of a Bullet (Rifle) is about 54.90 kilometers per minute.
(5.56 x 45 mm, a.k.a. 5.56 NATO)
A 5.56 x 45 mm cartridge is fired at a velocity of 54.90 kilometers per minute. 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-and-one-tenth times as fast as The Space Shuttle
The speed of The Space Shuttle is about 464.620 kilometers per minute.
(Orbiter vehicle velocity)
The space shuttle orbits at a speed of 464.620 kilometers per minute. 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-fifth as fast as a Meteor
The speed of a Meteor is about 2,500 kilometers per minute.
(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 670 kilometers per minute and 4,300 kilometers per minute, depending on their size. The fireball effect, known as ablation, ceases once the atmosphere has slowed the meteoroid to a velocity of about 170 kilometers per minute.
It's about one-tenth as fast as a bolt of Lightning
The speed of a bolt of Lightning is about 5,900 kilometers per minute.
(atmospheric electrical discharge)
A bolt of lightning can travel at up to 5,800 kilometers per minute when arcing from the atmosphere to the Earth. An estimated 280 million lightning strikes strikes occur each year.
It's about one-forty-thousandth as fast as The Speed of Light
The speed of The Speed of Light is about 17,987,547.480 kilometers per minute.
(C) (in a vacuum)
The speed of light (and all other electromagnetic radiation) in a perfect vacuum is known as "c" and measures 17,987,547.480 kilometers per minute, per the formal definition of the meter. While visible light travels close to this speed in air, it slows to 11,991,698.32020 kilometers per minute when passing through the glass of a typical window.
