LEGAL UNITS OF MEASUREMENT
1. SI UNITS AND THEIR DECIMAL MULTIPLES AND SUBMULTIPLES
1.1. SI base units
Quantity | Unit | |
Quantity | Name | Symbol |
Length Mass Time Electric current Thermodynamic temperature Amount of substance Luminous intensity | metre kilogram second ampere kelvin mole candela | m kg s A K mol cd |
Definitions of SI base units:
Unit of length
A metre is the length of the path travelled in a vacuum by light during 1/299 792
458 seconds.
Unit of mass
The kilogr am is the unit of mass; it is equal to the mass of the international prototype of the kilogram.
Unit of time
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 caesium
133 atom.
Unit of electric current
The ampere is that constant current which, if maintained in two straight parallel conductors of infinite length, of negligible circular
cross-article and placed one metre apart in a vacuum, would produce between the conductors a force equal to 2 x
10-7 newton per metre of length.
Unit of thermodynamic temperature
The kelvin, unit of thermodynamic temperature, is the fraction 1/273,16 of the thermodynamic temperature of the triple point of water.
This definition refers to water having the isotopic composition defined by the following amount-of-substance ratios: 0.00015576 mole
of 2 H per mole of 1 H,
0.0003799 mole of 17 O per mole of 16 O and 0.0020052 mole of 18 O per mole of
16 O.
Unit of amount of substance
1. The mole is the amount of substance of a system which contains as many elementary entities as there are atoms in 0.012 kg
of carbon 12.
2. When the mole is used, the elementary entities must be specified and may be

Unit of luminous intensity
The candela is the luminous intensity, in a given direction, of a source which emits monochromatic rays with a frequency of 540 x
1012 hertz and whose energy intensity in that direction is 1/683 watt per steradian.
1.1.1 Special name and symbol of the SI derived unit of temperature for expressing Celsius temperature
Quantity | Unit | |
Quantity | Name | Symbol |
Celsius temperature | degree Celsius | oC |
Celsius temperature t is defined as the diff er ence t = T - T0 betw een t he two thermodynami c temperatures T and T 0 where T 0 = 273,15 K. An interval or difference of temperature may be expressed either in kelvins or in degrees Celsius. The unit of "degrees
Celsius" is equal to the unit "kelvin".
1.2 SI derived units
Definitions of supplementary SI units:
Unit of plane angle
The radian is the angle between two radii of a circle cut off on the circumference of an arc equal in length to the radius.
Unit of solid angle
The steradian is the solid angle of a cone which, having its vertex in the centre of a sphere, cuts off on the surface of the sphere
an area equal to that of a square with sides of length equal to the radius of the sphere.

1.2.2. General rule for derived units
Units derived coherently from SI base units are given as algebraic expressions in the form of products of powers of the SI base units
with a numerical factor equal to
1.

The names and symbols of the decimal multiples and submultiples of the unit of mass are formed by attaching prefixes to the word ‘gram’
and their symbols to the symbol ‘g’.
Where a deriv e d uni t is ex pressed as a f r ac tio n, i t s d ecim a l m u lt ip les an d submultiples may be designated by attaching
a prefix to units in the numerator or the denominator, or in both these parts.
Compound prefixes, that is to say prefixes formed by the juxtaposition of several
of the above prefixes, may not be used.

FOURTH SCHEDULE (Article 14)
NAMES AND SYMBOLS USED IN
THE INTERNATIONAL SYSTEM OF UNITS "SI"
1. Definition
"SI" shall have the meaning assigned to it in article 2 of the Act.
2. SI unit symbols
SI unit symbols (and also many non-SI unit symbols) are written as follows:
2.1. Roman (upright) type is used for the unit symbols. In general, unit symbols are written in lower case, but, if the name of
the unit is derived from the proper name of a person, the first letter of the symbol is a capital. When the name of a unit is spelled
out, it is always written in lower case, except when the name is the first word of a sentence or is the name "degree Celsius".
2.2. Unit symbols are unaltered in the plural.
2.3. Unit symbols are not followed by a full stop (period), except as normal punctuation at the end of a sentence.
3. Algebra of SI unit symbols
In accord with the general principles adopted by ISO/TC 12 (ISO 31), the CIPM recomm en ds that algebraic expressi ons invol ving
SI u n it sym bols be expressed in standard forms.
3.1. Half-high dots or spaces are used to express a derived unit formed from two or more other units by multiplication.
Example: N · m or N m.
3.2 A solidus (oblique stroke, /), a horizontal line, or a negative exponent is used to express a derived unit formed from two
other units by division.
Example: m/s or m - s or m · s-1.
3.3. The solidus is not followed by a multiplication sign or by a division sign on the same line unless ambiguity is avoided by
parentheses. In complicated cases, negative exponents or parentheses are used to avoid ambiguity.
Examples: m/s2 or m · s-2 but not m/s/s
m · kg/(s3 · A) or m · kg · s-3 · A -1 but neither m · kg/s3 /A
nor m · kg/s3 · A.
4. Rules for using SI prefixes
In accord with the general principles adopted by the ISO (ISO 31), the CIPM
recommends that the following rules be observed when using the SI prefixes:
4.1. Prefix symbols are printed in roman (upright) type with no space between the prefix symbol and the unit symbol.
4.2. The grouping formed by the prefix symbol attached to the unit symbol constitutes a new inseparable symbol (of a
multiple or submultiple of the unit concerned) which can be raised to a positive or negative power and combined with other unit symbols
to form compound unit symbols.
Examples:
1 c m3 = (10-2 m )3 = 10-6 m3
1 µ s-1 = (10-6 s )-1 = 106 s-1
1 V/cm = (1 V) / (10-2 m) = 102 V / m
1 cm-1 = (10-2 m)-1 = 102 m-1.
4.3. Compound prefixes, i.e. prefixes formed by the juxtaposition of two or more
SI prefixes, are not used.
Example: 1 nm but not 1 mµm.
4.4. A prefix is never used in isolation.
Example: 106 /m3 but not M/m3.
