     5||'''__ATTACK NOTICE__ [[BR]] The UCUM web page is currently under heavy attack by spammers. The rate and intensity of the attack borders on cyber terrorism or at least sabotage. [[BR]] - The ticket system is currently under maintenance and new users currently cannot create new tickets until we have established spam filters and additional CAPTCHA challenges. You can contact any of the board members and send your inquiry that way for the time being. [[BR]] - If you have recently added a ticket that has not yet received a response, your ticket might be deleted in the cleanup process. You might save your ticket content, send it to one of the board members, or enter it again once you see this notice announce the re-opening of the ticket system. [[BR]] - If you are one of those spammers, save your time, nobody will see your stuff anyway. You will not succeed.'''

    57= The Unified Code for Units of Measure =
     
    1416The Unified Code for Units of Measure (UCUM) is a code system intended to include all units of measures being contemporarily used in international science, engineering, and business. The purpose is to facilitate unambiguous electronic communication of quantities together with their units. The focus is on electronic communication, as opposed to communication between humans. A typical application of The Unified Code for Units of Measure are electronic data interchange (EDI) protocols, but there is nothing that prevents it from being used in other types of machine communication.
    1517
    16 UCUM is based on the ISO 80000: 2009 Quantities and Units standards series that specify the use of System International (SI) units in publications. ISO 80000 standards series is developed by Technical Committee 12, International Organization of Standardization (ISO/TC12) Quantities and units in co-operation with Technical Committee 25, International Electrotechnical Committee (IEC/TC 25).
    17 
    18 ISO 80000 consists of the following parts, under the general title Quantities and units:
    19  * Part 1: General
    20  * Part 2: Mathematical signs and symbols to be used in the natural sciences and technology
    21  * Part 3: Space and time
    22  * Part 4: Mechanics
    23  * Part 5: Thermodynamics
    24  * Part 6: Electromagnetism
    25  * Part 7: Light
    26  * Part 8: Acoustics
    27  * Part 9: Physical chemistry and molecular physics
    28  * Part 10: Atomic and nuclear physics
    29  * Part 11: Characteristic numbers
    30  * Part 12: Solid state physics
    31  * Part 13: Information science and technology
    32  * Part 14: Telebiometrics related to human physiology.
    33        
    34 Thus, UCUM support EDI protocols for the quantities and units in the domains of knowledge specified in ISO 80000 standards parts 2-14 above
