International Classification of Diseases (ICD, ICDA)
The classification of specific conditions and groups of conditions determined by an internationally representative expert committee that advises the World Health Organization, which publishes the complete list in a periodically revised book, the Manual of the International Statistical Classification of Diseases, Injuries and Causes of Death. The Tenth Revision (ICD-10) came into use in 1992; it has 20 chapters, each with a hierarchical arrangement of subdivisions (rubrics); some chapters are etiological, some relate to body systems, some to classes of conditions, some to procedures.

International System of Units (SI)
A system of measurements, based on the metric system, adopted at the 11th General Conference on Weights and Measures of the International Organization for Standardization (1960) to cover both the coherent units (basic, supplementary, and derived units) and the decimal multiples and submultiples of these units formed by use of prefixes proposed for general international scientific and technological use. SI proposes seven basic units: meter (m), kilogram (kg), second (s), ampere (A), Kelvin (K), candela (cd), and mole (mol) for the basic quantities of length, mass, time, electric current, temperature, luminous intensity, and amount of substance, respectively; supplementary units proposed include the radian (rad) for plane angle and steradian (sr) for solid angle; derived units ( e.g., force, power, frequency) are stated in terms of the basic units ( e.g., velocity is in meters per second, m s−1). Multiples (prefixes) in descending order are: exa- (E, 1018), peta- (P, 1015), tera- (T, 1012), giga- (G, 109), mega- (M, 106), kilo- (k, 103), hecto- (h, 102), deca- (da, 101), deci- (d, 10−1), centi- (c, 10−2), milli- (m, 10−3), micro- (μ, 10−6), nano- (n, 10−9), pico- (p, 10−12), femto- (f, 10−15), atto- (a, 10−18). Proposed prefixes are zetta- (z, 1021), yotta- (y, 1024), zepto- (z, 10−21), and yocto- (y, 10−24). Those involving a multiple of 103 are recommended; compounds of these are not recommended ( e.g., mμ for n). [Fr. Système International d'Unités]
