second - 9192631770 periods of the readiation corresponding to the transition between the two hyperfine levels of the ground state of cesium-133 atom.

meter - distance that light travels in a vacuum during a time interval of 1/299792458 second.

ampere - the constant current which, if maintained in two straight parallel conductors of infinite length, of negligible circular cross section, and placed 1 meter apart in a vacuum, would produce between these conductors a force equal to 2·10^-7 newton per meter of length.

kelvin - unit of thermodynamic temperature, in the fraction 1/273.16 of the termodynamic temperature of the triple point of water.

candela - the luminous intensity, in a given direction, of a source that emits monochromatic radiation of frequency 540·10¹² hertz and has a radiant intensity in that direction of 1/683 watt per steradian.

mole - the amount of substance of a system which contains as many elementary entities as there are atoms in 0.012 kilogram of carbon 12.

kilogram - based on a standard kept in Sèvres, France.

radian - the angle between two radii of a circle which cut off on the circumference an arc equal in length equal in length to the radius.

steradian - the solid angle which, having its vertex in the center of a sphere, cuts off an area of the surface of the sphere equal to that of a square with sides of length equal to the radius of the sphere.
