STN Units System

The following provides complete information about the STN Units system. The STN Units system was developed to support the expression of Units information for search and retrieval within STN.

The STN Units system may also be used to express Units information within the Z39.50 protocol.

Introduction to STN Units System

The STN Units system was developed to support the expression of Units information for search and retrieval within STN.

The STN Units system is organized in a set of tables, corresponding to Unit Types. Within each Unit Type, the supported Units are listed. For example, the table for Unit Type = Length contains various supported length units supported by STN, such as meter, angstrom, and fathom. Where appropriate, conversion factors between the STN Units system and the SI units system are included for each supported unit.

The STN Units system may also be used to express Units information within the Z39.50 protocol. Read more about Using STN Units within Z39.50 below.

Table of Conversion Factors

1. Conversion factors are taken from "Quantities, Units and Symbols in Physical Chemistry (IUPAC, 1988), "Conversion Tables of Units for Science & Engineering (Ari L. Horvath, Elsevier, 1986), and "CRC Handbook of Chemistry and Physics" or are calculated directly from these publications. In most cases, unit symbols are taken from the recommendations in ISO 2955- 1974 (E). For units that did not appear in this publication, symbols were taken from the IUPAC publication cited above.

2. Both abbreviations and the entire unit name may be used, except for multi-word units. Since spaces are not allowed in the unit symbols, multi-word unit terms do not make a lot of sense, and thus are only represented by abbreviations.

3. The units conversion procedure will remove a terminal "s" from a unit designation if no designation with the appended "s" can be found. Thus plurals of unit designations need to be added to the conversion table only in those cases where the plural form is not created merely by adding an "s" to the singular form.

 

Using STN Units within Z39.50

Z39.50 is an American National Standard that specifies an interoperable protocol and services for information search and retrieval. The Z39.50 protocol specifies formats and procedures governing the exchange of messages between a client and server, enabling the client to request that the server search databases for information that meets specified criteria, and to retrieve some or all of the identified information.  

Within the Z39.50 protocol, units of measure are expressed using the following ASN.1 definition for Unit and IntUnit: 

 Unit ::= SEQUENCE{
 unitSystem [1] InternationalString OPTIONAL,
 unitType [2] StringOrNumeric OPTIONAL,
 unit [3] StringOrNumeric OPTIONAL,
 scaleFactor [4] IMPLICIT INTEGER OPTIONAL}

IntUnit is simply an integer value together with a unit, and is defined as: 

 IntUnit ::= SEQUENCE{
 value [1] IMPLICIT INTEGER,
 unitUsed [2] IMPLICIT Unit}

In the above definition: 

 Unit System provides the context for the unit type and unit.
 Systems in common use in the scientific and technical communities
 include SI, MKS, CGS, FPS, ENG, and STN. In addition to existing
 standard unit systems, the unit system 'z3950' will be used to
 register those unit types/units needed by implementors and not
 defined by other known systems. Values of unit type and unit under
 the system 'z3950'will be maintained by the Z39.50 Maintenance
 Agency.

 Unit Type is, for example, 'Mass'.

 Unit is, for example, 'Kilograms' (when unit type is 'Mass').

 Scale Factor is an integer scale factor, base 10. For example, 9
 would mean that the actual value is the given value times 10 to the
 9th power.

When using STN Units within Z39.50, the following conventions will be followed: 

 unitSystem = "STN"
 unitType = STN Unit Type (eg, "length")
 unit = STN unit (eg, "meter")

For further information on the Z39.50 standard, see the Z39.50 Maintenance Agency Home Page.

 

Unit Multipliers

Decimal multipliers for unit symbols are taken from the recommendations in ISO 2955-174 (E) and are listed below. Both the abbreviation and the complete name may be used. Decimal multipliers may be used with any unit symbol except for the symbols for temperature. Combinations of decimal multipliers and unit symbols that eliminate one or more of the vowels of each when combined are listed in the conversion table, e.g., micro + ohm = microhm.  

Multiplier Symbol            Factor by which the
                             unit is multiplied 

t, tera                      1E+12 = 10**12
g, giga                      1E+09 = 10**9
ma, mega                     1E+06 = 10**6
k, kilo                      1E+03 = 10**3
h, hecto                     1E+02 = 10**2
da, deca                     1E+01 = 10
d, deci                      1E-01 = 10**-1
c, centi                     1E-02 = 10**-2
m, milli                     1E-03 = 10**-3
u, micro                     1E-06 = 10**-6
n, nano                      1E-09 = 10**-9
p, pico                      1E-12 = 10**-12
f, femto                     1E-15 = 10**-15
a, atto                      1E-18 = 10**-18

 

Units Table

Notes about these tables:  

  • In the following table, unit symbols are often followed by the complete name of the unit in parentheses. The text in parentheses is not part of the abbreviation.
  • # after a conversion factor denotes a value that is accurate to +-5 in the rightmost digit.
  • (CRC) after a conversion factor denotes a value taken from the CRC Handbook of Chemistry and Physics.
