How fast is 745 knots?

It's about one-and-one-tenth times as fast as The Speed of Sound
The speed of The Speed of Sound is about 667 knots.
(in dry air at 20°C)
The speed of sound in dry air at 20°C (68°F) is 667 knots. Air is a relatively poor acoustic conductor, however, as sound will travel at speeds of between 2,910 knots to 3,030 knots in water, depending on its salinity.
It's about as fast as a Bullet (Handgun)
The speed of a Bullet (Handgun) is about 746 knots.
(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 745 knots. This type of ammunition has been the standard issue round of the United States Federal Bureau of Investigation (FBI) since 1990.
It's about three-fifths as fast as a Jet Fighter
The speed of a Jet Fighter is about 1,300 knots.
(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 1,300 knots. The F-16 has a flight ceiling of approximately 15 km (9.32 mi).
It's about two-fifths as fast as a Bullet (Rifle)
The speed of a Bullet (Rifle) is about 1,780 knots.
(5.56 x 45 mm, a.k.a. 5.56 NATO)
A 5.56 x 45 mm cartridge is fired at a velocity of 1,780 knots. 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-twentieth as fast as The Space Shuttle
The speed of The Space Shuttle is about 15,052 knots.
(Orbiter vehicle velocity)
The space shuttle orbits at a speed of 15,052 knots. 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-one-hundredth as fast as a Meteor
The speed of a Meteor is about 82,000 knots.
(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 22,000 knots and 140,000 knots, depending on their size. The fireball effect, known as ablation, ceases once the atmosphere has slowed the meteoroid to a velocity of about 5,400 knots.
It's about one-two-hundred-fiftieth as fast as a bolt of Lightning
The speed of a bolt of Lightning is about 190,000 knots.
(atmospheric electrical discharge)
A bolt of lightning can travel at up to 190,000 knots when arcing from the atmosphere to the Earth. An estimated 280 million lightning strikes strikes occur each year.
It's about one-eight-hundred-thousandth as fast as The Speed of Light
The speed of The Speed of Light is about 582,749,918.358530 knots.
(C) (in a vacuum)
The speed of light (and all other electromagnetic radiation) in a perfect vacuum is known as "c" and measures 582,749,918.358530 knots, per the formal definition of the meter. While visible light travels close to this speed in air, it slows to 388,499,945.578830 knots when passing through the glass of a typical window.
