 It's about 0.000000000003 times as fast as The Speed of Light. In other words, 123 inches per hour is 0.000000000002894780410 times the speed of The Speed of Light, and the speed of The Speed of Light is 345,449,346,000 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 42,490,269,600,000 inches per hour, per the formal definition of the meter. While visible light travels close to this speed in air, it slows to 28,326,846,400,000 inches per hour when passing through the glass of a typical window. It's about 0.000000009 times as fast as a bolt of Lightning. In other words, 123 inches per hour is 0.00000000890 times the speed of a bolt of Lightning, and the speed of a bolt of Lightning is 110,000,000 times that amount. (atmospheric electrical discharge)A bolt of lightning can travel at up to 14,000,000,000 inches per hour when arcing from the atmosphere to the Earth. An estimated 280 million lightning strikes strikes occur each year. It's about 0.00000002 times as fast as a Meteor. In other words, 123 inches per hour is 0.0000000210 times the speed of a Meteor, and the speed of a Meteor is 48,000,000 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 1,600,000,000 inches per hour and 10,000,000,000 inches 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 390,000,000 inches per hour. It's about 0.0000001 times as fast as The Space Shuttle. In other words, 123 inches per hour is 0.000000112070 times the speed of The Space Shuttle, and the speed of The Space Shuttle is 8,923,000 times that amount. (Orbiter vehicle velocity)The space shuttle orbits at a speed of 1,097,500,000 inches 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 0.0000010 times as fast as a Bullet (Rifle). In other words, 123 inches per hour is 0.0000009480 times the speed of a Bullet (Rifle), and the speed of a Bullet (Rifle) is 1,050,000 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 130,000,000 inches 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-seven-hundred-fifty-thousandth as fast as a Jet Fighter. In other words, the speed of a Jet Fighter is 770,000 times 123 inches 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 94,000,000 inches per hour. The F-16 has a flight ceiling of approximately 15 km (9.32 mi). It's about one-four-hundred-fifty-thousandth as fast as a Bullet (Handgun). In other words, 123 inches per hour is 0.000002260 times the speed of a Bullet (Handgun), and the speed of a Bullet (Handgun) is 442,000 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 54,300,000 inches per hour. This type of ammunition has been the standard issue round of the United States Federal Bureau of Investigation (FBI) since 1990.
