Closest first | Highest first | Lowest first

It's about 0.0000000002 times as fast as The Speed of Light.
In other words, 128 inches per minute is 0.0000000001807472640 times the speed of The Speed of Light, and the speed of The Speed of Light is 5,532,587,200 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 exactly 708,171,161,000 inches per minute, per the formal definition of the meter. While visible light travels close to this speed in air, it slows to 472,114,107,000 inches per minute when passing through the glass of a typical window.
It's about 0.0000006 times as fast as a bolt of Lightning.
In other words, 128 inches per minute is 0.000000550 times the speed of a bolt of Lightning, and the speed of a bolt of Lightning is 1,800,000 times that amount.
(atmospheric electrical discharge)
A bolt of lightning can travel at up to 230,000,000 inches per minute when arcing from the atmosphere to the Earth. An estimated 280 million lightning strikes strikes occur each year.
It's about one-seven-hundred-fifty-thousandth as fast as a Meteor.
In other words, the speed of a Meteor is 770,000 times 128 inches 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 26,000,000 inches per minute and 170,000,000 inches 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 6,600,000 inches per minute.
It's about one-one-hundred-fifty-thousandth as fast as The Space Shuttle.
In other words, 128 inches per minute is 0.00000699760 times the speed of The Space Shuttle, and the speed of The Space Shuttle is 142,910 times that amount.
(Orbiter vehicle velocity)
The space shuttle orbits at a speed of 18,292,000 inches 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-fifteen-thousandth as fast as a Bullet (Rifle).
In other words, the speed of a Bullet (Rifle) is 16,900 times 128 inches 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 2,160,000 inches 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-ten-thousandth as fast as a Jet Fighter.
In other words, the speed of a Jet Fighter is 12,000 times 128 inches 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 1,600,000 inches per minute. The F-16 has a flight ceiling of approximately 15 km (9.32 mi).
It's about one-seven-thousandth as fast as a Bullet (Handgun).
In other words, 128 inches per minute is 0.000141 times the speed of a Bullet (Handgun), and the speed of a Bullet (Handgun) is 7,090 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 906,000 inches per minute. This type of ammunition has been the standard issue round of the United States Federal Bureau of Investigation (FBI) since 1990.
