In Wikipedia speed of light is defined as 'in international distance of units (SI) the meter is defined as the distance of light traveled in vac-cum in 1/299,792,458 of the second. This definition fixes the speed of light at 'exactly' 299,792,456 meters/second. This definition is the 'classic' example of what is called as 'circular logic'. When it comes to shape of kidney, you say that it is bean shaped. When it comes to shape of bean, you say, it is kidney shaped. Here you take the help of meter to define the speed of light and when it comes to length of meter, you take the help of speed of light.

No, there's nothing circular about it. The speed of light isn't a "definition", it's a physical fact.
