The metre was originally defined as one ten-millionth of the distance from the North Pole to the equator a;ong the meridian going through Paris. As the measurement of the earth improved, the metre had to be recalibrated. That is not much use for something that is meant to be a standard, So in 1983 it was redefined as the distance travelled by light, in vacuum, in 1/299792458 second.

It was not. The current definition was established in 1983.
standard was changed to be associated with the constant speed of light
In 1983, the standard meter was defined in terms of the speed of light. Specifically, the meter was defined as the length of the path traveled by light in a vacuum during a specific fraction of a second.

kength of a meter
The SI unit for length is the meter. However, because the meter is so large, in the laboratory derivatives of the meter are often used. These are formed by adding a prefix to the word meter. For instance the centimeter, a commonly used unit, is equal to 1/100 of a meter.
