"The meter is the length of the path traveled by light in vacuum during a time interval of 1/299,792,458 of a second.Note that the effect of this definition is to fix the speed of light in vacuum at exactly 299,792,458 m/s."
I don't understand this because how can you use a number based on the meter to go back and define the meter? In other words, if light travels at x METERS / second. How can you use x METERS / second to define what a meter is?
