How is a meter determined?
The metre is currently defined as the length of the path travelled by light in a vacuum in 1299 792 458 of a second. The metre was originally defined in 1793 as one ten-millionth of the distance from the equator to the North Pole along a great circle, so the Earth’s circumference is approximately 40000 km.

What is the advantage of defining Metre in terms of velocity of light?
Answer. Answer: The biggest advantage of the same is that the wavelength of light does not changes with time, pressure, temperature, etc. Moreover, it can be easily reproducible due to the presence of krypton everywhere.
Is the meter defined by the speed of light?
The speed of light is actually DEFINED to be 299,792,458m/s. The meter is actually defined as one 299,792,458′th of the distance light travels in one second in a perfect vacuum. This is what then makes the speed of light such a perfectly known number; it is defined to be that number.
