ISO (the International Organization for Standardization) is a worldwide federation of national standards

bodies (ISO member bodies). The work of preparing International Standards is normally carried out

through ISO technical committees. Each member body interested in a subject for which a technical

committee has been established has the right to be represented on that committee. International

organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO

collaborates closely with the International Electrotechnical Commission (IEC) on all matters of

ISO 80000 consists of the following parts, under the general title Quantities and units:

IEC 80000 consists of the following parts, under the general title Quantities and units:

ISO 80000-3 gives names, symbols, definitions, and units for quantities of space and time.

The following documents, in whole or in part, are normatively referenced in this document and are

indispensable for its application. For dated references, only the edition cited applies. For undated

references, the latest edition of the referenced document (including any amendments) applies.

The names, symbols, definitions, and units for quantities of space and time are given on the following

3-1.1 length l, L linear extent in space between any two m Length need not necessarily be measured along a

3-1.2 width, b, B minimum length of a straight line segment m This quantity is non-negative.

3-1.3 height, h, H minimum length of a straight line segment m This quantity is usually signed. The sign expresses

depth, between a point and a reference line or the position of the particular point with respect to

3-1.5 diameter d, D width (item 3-1.2) of a circle, cylinder or m This quantity is non-negative.

3-1.6 radius r, R half of a diameter (item 3-1.5) m This quantity is non-negative.

3-1.7 path length, s length of a rectifiable curve between two of m The differential path length at a given point of a

3-1.8 distance d, r shortest path length (item 3-1.7) between m A metric space might be curved. An example of a

3-1.9 radial distance r , ρ distance (item 3-1.8), where one point is m The subscript Q denotes the point from which the

3-1.10 position vector r vector (ISO 80000-2) from the origin of a m Position vectors are so-called bounded vectors, i. e.

co-ordinate system to a point in space their magnitude and direction depends on the

3-1.11 displacement Δr vector (ISO 80000-2) between any two m Displacement vectors are so-called free vectors, i. e.
