The speed of light is the speed light propogates in a vacuum. Light is photons, a massless particle. The speed of light is also the slowest speed which is faster than any particle with mass can move: that is, no particle with mass can be accelerated to the speed of light, but you can get it arbitrarily close to that speed by addig more force.

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, or almost one foot per nanosecond.
