Metric System Mastery

One metre is the mass of a platinum-iridium cylinder kept at the National Bureau of Weights and Measurements, Paris.

One metre is that current which, when passed through two straight parallel conductors of infinite length and of negligible cross-section kept at a distance of 1 metre apart in the vacuum, produces between them a force equal to 2 x 10^-7 newton per metre length.

One metre is the time taken by the light of a specified wavelength emitted by a caesium-133 atom to execute 9192631770 vibrations.

One metre is the distance travelled by light in the vacuum during a time interval of (1/299792458) seconds. (correct)

One kilogram is that current which, when passed through two straight parallel conductors of infinite length and of negligible cross-section kept at a distance of 1 metre apart in the vacuum, produces between them a force equal to 2 x 10^-7 newton per metre length.
