A meter is the SI unit of distance. The meter is defined as the length of the path travelled by light in vacuum during a time interval of 1/299 792 458 of a second.[1] The reason that the meter is defined as a measure of time is due to the much higher accuracy of time measurements than length measurements (at the time of the definition, time could be measured to 1 part in 1013 whereas length could only be measured to 4 parts in 109).[2]
