The speed of light in vacuum, usually denoted by c, is a universal physical constant important in many areas of physics. Its value is 299,792,458 metres per second, a figure that is exact since the length of the metre is defined from this constant and the international standard for time.[1] In imperial units this speed is approximately 186,282 miles per second.

How fast does light travel in miles per second AND meters per second?
The speed of light in vacuum is:186,282 miles per second.299,792,458 meters per second.
If a fish swims 0.09 centimeters every hundredth of a second how fast in meters per second is it swimming?
Since a centimeter is 100th of a meter, it would be traveling at .09 meters per second. 100th of a second, 100th of a meter, the relationship is 1. meters per second.
How fast does an airplane travel per second?
At 550 miles per hour, it would be .15 miles per second.
How fast does light travel through space in miles per hour?
670 616 629 mph
How fast can electricity travel in one second?
The electrical current (or signal) travels at about 2/3 the speed of light in a vacuum - that is, it travels at approximately 200,000 km/sec. Note that individual electrons move slower than that.
