International System of Units (SI)
Measures (CGPM) in 1960. It is a coherent system of units built from seven SI base units, one for each
of the seven dimensionally independent base quantities: the meter, kilogram, second, ampere, kelvin,
mole, and candela, for the dimensions length, mass, time, electric current, thermodynamic temperature,
amount of substance, and luminous intensity, respectively. The definitions of the SI base units are given
below. The SI derived units are expressed as products of powers of the base units, analogous to the
corresponding relations between physical quantities but with numerical factors equal to unity.
In the International System there is only one SI unit for each physical quantity. This is either the
appropriate SI base unit itself or the appropriate SI derived unit. However, any of the approved decimal
prefixes, called SI prefixes, may be used to construct decimal multiples or submultiples of SI units.
It is recommended that only SI units be used in science and technology (with SI prefixes where
appropriate). Where there are special reasons for making an exception to this rule, it is recommended
always to define the units used in terms of SI units. This section is based on information supplied by
IUPAC.
792 458 of a second (17th CGPM, 1983).
Kilogram — The kilogram is the unit of mass; it is equal to the mass of the international prototype
of the kilogram (3rd CGPM, 1901).
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 cesium-133 atom (13th CGPM,
1967).
Ampere — The ampere is that constant current which, if maintained in two straight parallel conduc-
tors of infinite length, of negligible circular cross-section, and placed 1 meter apart in vacuum,

(9th CGPM, 1948).
Kelvin — The kelvin, unit of thermodynamic temperature, is the fraction 1/273.16 of the thermody-
namic temperature of the triple point of water (13th CGPM, 1967).
Mole — The mole is the amount of substance of a system that contains as many elementary entities
must be specified and may be atoms, molecules, ions, electrons, or other particles, or specified
groups of such particles (14th CGPM, 1971).
Examples of the use of the mole:

1 mol of Hg 2 2
has a mass of 401.18 g and a charge of 192.97 kC
1 mol of Fe 0.91 S has a mass of 82.88 g

Candela — The candela is the luminous intensity, in a given direction, of a source that emits
direction of (1/683) watt per steradian (16th CGPM, 1979).

1 For radial (circular) frequency and for angular velocity, the unit rad s –1 , or simply s –1 ,
should be used, and this may not be simplified to Hz. The unit Hz should be used only
for frequency in the sense of cycles per second.

The SI unit of Celsius temperature interval is the degree Celsius, °C, which is equal to the
kelvin, K. °C should be treated as a single symbol, with no space between the ° sign and
the letter C. (The symbol °K, and the symbol °, should no longer be used.)

Units in Use Together with the SI
These units are not part of the SI, but it is recognized that they will continue to be used in appropriate
megaelectronvolt, MeV; and kilotonne, ktonne.

1 The ångstrom and the bar are approved by CIPM for “temporary use with
SI units,” until CIPM makes a further recommendation. However, they
should not be introduced where they are not used at present.
2 The values of these units in terms of the corresponding SI units are not
exact, since they depend on the values of the physical constants e (for the
electronvolt) and N A (for the unified atomic mass unit), which are deter-
mined by experiment.
3 The unified atomic mass unit is also sometimes called the dalton, with
symbol Da, although the name and symbol have not been approved by
CGPM.
