The speed of light in vacuum, commonly denoted c, is a universal physical constant important in many areas of physics. Its exact value is defined as 299792458 metres per second. Astronomical units per day: 173 Miles per second: 186000 Miles per hour: 671000000 Metres per second: 299792458 Kilometres per hour: 1080000000 Parsecs per year: 0.307

243Depends on the medium...at it's highest(i.e in vaccum) it goes about 300 million meters per second, but in Rubidium semiconductor kept well below room temperature it can travel as slow as 17m/s.
