Speed of light is speed unit, symbol: [c]. Definition of 1 speed of light ≡ 299 792 458 m/s. Light velocity (in vacuum) is one of the basic physical constants. Sign c (Latin celeritas = speed). Its value is exactly: 299792458 m/s. Example: electromagnetic waves propagation speed 1 c.. Compared to metre per second, speed of light is bigger unit.
• 1 [c] = (exactly) `299792458` [m/s]
• 1 [m/s] = (exactly) `1/(299792458)` [c] = 3.3356409519815 × 10-9 [c]
Multiply convert of speed of light to common speed units:[c]
