 It's about 0.000000009 times as fast as The Speed of Light In other words, 390,000 inches per hour is 0.00000000917857202531760 times the speed of The Speed of Light, and the speed of The Speed of Light is 108,949,409.259050 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 42,490,269,611,030 inches per hour, per the formal definition of the meter. While visible light travels close to this speed in air, it slows to 28,326,846,407,826 inches per hour when passing through the glass of a typical window. It's about one-thirty-five-thousandth as fast as a bolt of Lightning In other words, the speed of a bolt of Lightning is 36,000 times 390,000 inches per hour. (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 one-fifteen-thousandth as fast as a Meteor In other words, the speed of a Meteor is 15,000 times 390,000 inches 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 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 one-three-thousandth as fast as The Space Shuttle In other words, 390,000 inches per hour is 0.00035535 times the speed of The Space Shuttle, and the speed of The Space Shuttle is 2,814.10 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 one-three-hundred-fiftieth as fast as a Bullet (Rifle) In other words, 390,000 inches per hour is 0.00301 times the speed of a Bullet (Rifle), and the speed of a Bullet (Rifle) is 332 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-two-hundred-fiftieth as fast as a Jet Fighter In other words, the speed of a Jet Fighter is 240 times 390,000 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 95,000,000 inches per hour. The F-16 has a flight ceiling of approximately 15 km (9.32 mi). It's about one-one-hundred-fiftieth as fast as a Bullet (Handgun) In other words, 390,000 inches per hour is 0.00717 times the speed of a Bullet (Handgun), and the speed of a Bullet (Handgun) is 139 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.
