How fast is 6 miles per hour?
It's about one-one-hundred-fiftieth as fast as The Speed of Sound
The speed of The Speed of Sound is about 767 miles per hour.
(in dry air at 20°C)
The speed of sound in dry air at 20°C (68°F) is 767 miles per hour. Air is a relatively poor acoustic conductor, however, as sound will travel at speeds of between 3,350 miles per hour to 3,490 miles per hour in water, depending on its salinity.
It's about one-one-hundred-fiftieth as fast as a Bullet (Handgun)
The speed of a Bullet (Handgun) is about 859 miles per hour.
(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 857 miles per hour. This type of ammunition has been the standard issue round of the United States Federal Bureau of Investigation (FBI) since 1990.
It's about one-two-hundred-fiftieth as fast as a Jet Fighter
The speed of a Jet Fighter is about 1,500 miles per hour.
(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 1,500 miles per hour. The F-16 has a flight ceiling of approximately 15 km (9.32 mi).
It's about one-three-hundred-fiftieth as fast as a Bullet (Rifle)
The speed of a Bullet (Rifle) is about 2,050 miles per hour.
(5.56 x 45 mm, a.k.a. 5.56 NATO)
A 5.56 x 45 mm cartridge is fired at a velocity of 2,050 miles per hour. 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-three-thousandth as fast as The Space Shuttle
The speed of The Space Shuttle is about 17,322 miles per hour.
(Orbiter vehicle velocity)
The space shuttle orbits at a speed of 17,322 miles per hour. 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-fifteen-thousandth as fast as a Meteor
The speed of a Meteor is about 94,000 miles per hour.
(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 25,000 miles per hour and 160,000 miles per hour, depending on their size. The fireball effect, known as ablation, ceases once the atmosphere has slowed the meteoroid to a velocity of about 6,200 miles per hour.
It's about one-thirty-five-thousandth as fast as a bolt of Lightning
The speed of a bolt of Lightning is about 220,000 miles per hour.
(atmospheric electrical discharge)
A bolt of lightning can travel at up to 220,000 miles per hour when arcing from the atmosphere to the Earth. An estimated 280 million lightning strikes strikes occur each year.
It's about 0.000000009 times as fast as The Speed of Light
The speed of The Speed of Light is about 670,616,629.38440 miles per hour.
(C) (in a vacuum)
The speed of light (and all other electromagnetic radiation) in a perfect vacuum is known as "c" and measures 670,616,629.38440 miles per hour, per the formal definition of the meter. While visible light travels close to this speed in air, it slows to 447,077,752.930390 miles per hour when passing through the glass of a typical window.
