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 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.
186,282.397 miles per second or 670,616,629.384 miles per hour
20mph
186,282 miles per hour
186,000 mi/sec x 3600 sec/hr= about 670.5 million mph
and in km/s:
299,792.458 in vacuum
actually, it depends on the material where it goes through.
I don't know but slow down when you go past all the bl**dy speed cameras

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.
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.
669,600,000 mph - though a vacum
504,000,000 mph - though water
186,000 miles per second - though a vacum
140,000 miles per second - though water
300,000 kilometers per second - though a vacum
225,940 kilometers per second - though water
1,080,000,000 km/h - through a vacum
813,384,000 km/h - though water
680400000mph

Talk about shooting yourself in the foot ! ;o))
fast, but slower then a tachyon
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.
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
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
no the speed of light is in metre/second and not mph its value is 3*10^8 m/s
Approx. 186,000 miles per second.
