How fast is 173 kilometers per minute?

Sort Order:
Closest first | Highest first | Lowest first

It's about two-fifths as fast as The Space Shuttle
In other words, 173 kilometers per minute is 0.372350 times the speed of The Space Shuttle, and the speed of The Space Shuttle is 2.68560 times that amount.
(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 three times as fast as a Bullet (Rifle)
In other words, 173 kilometers per minute is 3.150 times the speed of a Bullet (Rifle), and the speed of a Bullet (Rifle) is 0.3170 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 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 four-and-a-half times as fast as a Jet Fighter
In other words, the speed of a Jet Fighter is 0.230 times 173 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 seven-and-a-half times as fast as a Bullet (Handgun)
In other words, 173 kilometers per minute is 7.510 times the speed of a Bullet (Handgun), and the speed of a Bullet (Handgun) is 0.1330 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 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 eight-and-a-half times as fast as The Speed of Sound
In other words, 173 kilometers per minute is 8.410 times the speed of The Speed of Sound, and the speed of The Speed of Sound is 0.1190 times that amount.
(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 one-fifteenth as fast as a Meteor
In other words, the speed of a Meteor is 14 times 173 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 thirty times as fast as a Peregrine Falcon
In other words, 173 kilometers per minute is 26.70 times the speed of a Peregrine Falcon, and the speed of a Peregrine Falcon is 0.0375 times that amount.
(a.k.a. Peregrine, a.k.a. Duck Hawk, Falco peregrinus)
The Peregrine Falcon can reach speeds of up to 6.480 kilometers per minute when diving. Falcons are sometimes sent to scare smaller birds away from airports to improve air traffic safety and were used in World War II to intercept carrier pigeons used by enemy forces.
