What is the speed of light?
The speed of light is 186,000 miles per second or 299,792,458 meters per second or the time it takes for the light to turn green before the guy behind you starts honking. When people refer to light, they are referring to light in a vacuum, though many vacuums are so full of dirt and dust and cat hair that not much light can travel through it.

Light travels at a constant, finite speed of 186,000 mph . A traveler, moving at the speed of light, would circum-navigate the equator approximately 7.5 times in one second. By comparison, a traveler in a jet aircraft, moving at a ground speed of 500 mph, would cross the continental U.S. once in 4 hours.

how about this to get your brains all screwed up? In an experiment with different forms of matter, scientists have been able to slow down the speed of light to about 38 miles per hour and, according to the article from 1999, were planning on going slower.

Speed of light is now defined to be 299,792,458 meters per second. Inch is defined to be .0254 meters, divide by this to get inches. Divide by 12 to get feet. Divide by 5280 to get statute miles. Speed in miles/second is 186,282.3971. Multiply by 3600 to get:
670,616,629.387 miles per hour.
