34(6) base unit of time shall be second, which 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 caesium 133 atom
(7) base unit of electric current shall be ampere, which is the constant current
which, if maintained in two straight parallel conductors of infinite length, of negligible
circular cross-section, and placed 1 metre apart in vacuum, would produce between these
conductors a force equal to 2 × 10−7newton per metre of length.
(8) base unit of thermodynamic temperature shall be kelvin, which is thefraction 1 ⁄ 273.16 of the thermodynamic temperature of the triple point of water.
kelvin unit shall be used for the indication of temperature range, or thedifference of the temperature as well.
In any activity, degree Celsius may be used.
temperature in Celsius shall equals thermodynamic temperature minus
273.15(9) base unit of the amount of substance shall be Mole, which is the amountof substance of a system which contains as many elementary entities as there are atoms in
0.012 kilogram of carbon-12. When the Mole is used, the elementary entities must be
specified and may be atoms, molecules, ions, electrons, other particles, or specified groupsof such particles.
(10) base unit of luminous intensity shall be candela, which 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 in that direction of 1/683 watt per steradian.
