metre : The metre is the length of the path travelled by light in vacuum during a time interval of
1/299 792 458 of a second.
.2
[CGPM 1 .. 2444 (.. 1901)]kilogram : The kilogram is the unit of mass ; it is equal to the mass of the international prototype of the
kilogram.
.3 9 192 631 770 133[CGPM 13 .. 2510 (.. 1967) 1]
second : The 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 cesium133 atom.
.4 2 1 2 x 10-71 [CGPM .. 2489 (.. 1946) 2 CGPM 9 .. 2491 (.. 1948)]
ampere : The ampere is that constant electric current which, if maintained in two straight parallel
conductors infinite length, of negligible circular crosssection, and placed 1 metre apart in vacuum
would produce between these conductors a force equal to 2 x 10
-7
newton per metre of length.

kelvin : The kelvin, unit of thermodynamic temperature, is the fraction 1/273, 16 of the thermodynamic
temperature of the triple point of water.
NOTES
5 The 13th CGPM (1967), Resolution 3 also decided that the unit kelvin and its symbol K should be used
to express an interval of a difference of temperature
6 In addition to the thermodynamic temperatrue (symbol T), expressed in kelvins, use is also made of
Celsius temperature (symbol t) difined by the equation t = TTo, where To= 273.15 K by definition. To
express Celsius temperature, the unit degree Celsius, which is equal to the unit kelvin, is used ; in this
case, degree Celsius is a special name used in place of kelvin. An interval of difference of Celsius
temperature can, however, be expressed in kelvins ad well as in degrees Celsius.

mole : The mole is the amount of 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, of specified groups of such
particles.

radiation of frequency 540 x 1012hertz and of which the radiant intensity in that direction is 1/683
watt per steradian.
