The speed of light in the future is not the current "meter", wiki entry: meter (unit)

Meter (French: mètre, Hong Kong is called meter, Taiwan is called meter), China is also called meter, and Taiwan is sometimes called meter. The old translation "Midang" and "Mida" is the basic unit of length in the International System of Units , The symbol is m.

The length of 1 meter was originally defined as one ten millionth of the distance from the earth's equator to the North Pole through the meridian of Paris.

Later, as people's understanding of metrology deepened, the definition of the length of a meter was revised several times.Since 1983, the length of a meter has been defined as "the distance that light travels within 1/299792458 seconds in a vacuum." According to this definition, light travels about 300 million meters per second in a vacuum.

The following are the settings in this book:

In the future, the definition of meters will be revised again. First, define the imperial time system of 1 second, and then divide the distance of light for 1 second into 300 million integers. Because in the universe era, the speed of light is used in more places. After leaving the earth environment, it should be used. Compared with the unit system of the universal environment, integers are more convenient to use.

However, I am a little bit overwhelmed here, and sometimes there are errors, errors, and mistakes in detail conversion. Please understand, and please forgive me.
