How fast is 0.2130 miles per second?

Sort Order:
Closest first | Highest first | Lowest first

It's about one-eight-hundred-fifty-thousandth as fast as The Speed of Light
In other words, 0.2130 miles per second is 0.00000114342526922410 times the speed of The Speed of Light, and the speed of The Speed of Light is 874,565.244371920 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 186,282.397051220 miles per second, per the formal definition of the meter. While visible light travels close to this speed in air, it slows to 124,188.264702890 miles per second when passing through the glass of a typical window.
It's about one-three-hundredth as fast as a bolt of Lightning
In other words, 0.2130 miles per second is 0.0035 times the speed of a bolt of Lightning, and the speed of a bolt of Lightning is 290 times that amount.
(atmospheric electrical discharge)
A bolt of lightning can travel at up to 60 miles per second when arcing from the atmosphere to the Earth. An estimated 280 million lightning strikes strikes occur each year.
It's about one-one-hundredth as fast as a Meteor
In other words, 0.2130 miles per second is 0.0082 times the speed of a Meteor, and the speed of a Meteor is 120 times that amount.
(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 6.90 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 1.70 miles per second.
It's about one-twenty-fifth as fast as The Space Shuttle
In other words, 0.2130 miles per second is 0.044268 times the speed of The Space Shuttle, and the speed of The Space Shuttle is 22.590 times that amount.
(Orbiter vehicle velocity)
The space shuttle orbits at a speed of 4.81170 miles 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 two-fifths as fast as a Bullet (Rifle)
In other words, 0.2130 miles per second is 0.3750 times the speed of a Bullet (Rifle), and the speed of a Bullet (Rifle) is 2.670 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 0.5690 miles 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 half as fast as a Jet Fighter
In other words, 0.2130 miles per second is 0.510 times the speed of a Jet Fighter, and the speed of a Jet Fighter is 2 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 0.420 miles per second. The F-16 has a flight ceiling of approximately 15 km (9.32 mi).
It's about nine-tenths as fast as a Bullet (Handgun)
In other words, 0.2130 miles per second is 0.8930 times the speed of a Bullet (Handgun), and the speed of a Bullet (Handgun) is 1.120 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 0.2380 miles per second. This type of ammunition has been the standard issue round of the United States Federal Bureau of Investigation (FBI) since 1990.
