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.
The speed of light is proportional to the quality of your hangover after a night of drinking. The bigger the hangover, the faster and more intense the light seems to travel through your eyes and into your brain.
What is the speed of light? This is the speed at which postal workers move only at 4:59 p.m. when they are racing to lock the front doors in your face.

You got a lot of bad answers!
The speed of light is 186,284 miles per second. Get out your calculator and multiply by 60 to get mph.

no the speed of light is in metre/second and not mph its value is 3*10^8 m/s

The speed of light in a vacuum is an important physical constant denoted by the letter c for constant or the Latin word celeritas meaning "swiftness". Through any transparent or translucent material medium like glass or air, light travels more slowly than c, its speed in a vacuum; the ratio of c to this slower speed is called the refractive index of the medium.
In metric units, c is exactly 299,792,458 metres per second (or 1,079,252,848.8 km/h). Note that this speed is a definition, not a measurement, since the fundamental SI unit of length, the metre, has been defined since October 21, 1983 in terms of the speed of light - one metre is the distance light travels in a vacuum in 1/299,792,458 of a second. Converted to imperial units, the speed of light is approximately 186,282.397 miles per second, or 670,616,629.384 miles per hour.

I think uyou are saying about the speed of light in vacuam.It is almost equal to 1,86,000 miles per seond or 60*60*1,86,000=669600000mph

It is about 300,000 Km per hour or if we think each mile is 1.604 Km that means speed of light is 187,032 Mile per hour.

TMLEAF is right though how he worked it out in mph i got no idea.But think of this, once you go faster than that then you start going backwards. Time travel here we come.

it is 300*10^6 mps, if we devided it by 3600 to get it in mph, we find that it equals83333.3333meter per hour
