Description about eBook : DEFINITIONS OF SI UNITS

Metre (m) : One metre defined as the length of the path travelled by light in vacuum in 1/(299, 792,458) of a second. (1983).
Kilogram (kg) : One kilogram is the mass of prototype [a certain platinum-iridium cylinder] preserved at the International Bureau of Weights and Measures, at Severs, near Paris. (1889).
Second (s) : One second is the duration of 9,192,631,770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the cesium-133 atom. (1967).
Ampere (A) : One ampere is that constant current which , if maintained in two straight parallel conductors of infinite length, of neglegible circular cross-section, and placed 1 metre apart in vacuum would produce between these conductors a force equal to 2 × 10–7 newton per metre of length. (1946).
Kelvin (K) : One Kelvin is the fraction 1/(273.16) of the thermodynamic temperature of the triple point of water. (1967).
Candela (Cd) : One candela is the luminous intensity, in a given direction, of a source that emits monochromatic radiation of frequency 540 × 1012 hertz and that has a radiant intensity of 1/683 watt per steradian in that direction.
Mole (mol) : One mole is that amount of substance which contains as many elementary entities as there are atoms in 0.012 kg of carbon-12 isotope. The entities may be atoms, molecules, ions etc.............
