POSC Units of Measure Dictionary v2.2 2006-05-02 2006-05-02 John Bobbitt File created and immediately implemented. Changes based on feedback from users. The data in the Units of Measure dictionary are for public use, and may be used by anyone at their own risk. POSC does not guarantee or warrant the information as being correct. 2002-05-29 John Bobbitt Original Release of the dictionary 2004-02-26 John Bobbitt Version 2.0 of the schema allows more information. Also, many additional units were added to fill in needs from other groups. Also added were unit symbols for RP66 units model for many of the units (using the SameUnit element). 2004-03-18 John Bobbitt Review of 2004-02-26 release led to some minor corrections. 2004-04-22 John Bobbitt Review of 2004-03-18 release led to some minor corrections. 2005-02-08 John Bobbitt Changed the meaning of the Authority. They are: SI = Unit is defined in the SI system. POSC = unit added by, and defined by POSC. WITSML = additional unit declared by WITSML 1.2 as being needed. 2005-08-02 John Bobbitt Added two new uoms: dB/km and tonUS/ft2 2006-02-08 John Bobbitt Deprecated psia and psig in favor of psi. Use context to determine if psi is absolute or gauge (usually gauge). Also deprecated baud in favor of bits per second. 2006-05-02 John Bobbitt The usage of moles was off by a factor of 1000. The dictionary had consistently used mol(kg) as the the basic unit, rather than mole. The errors involved 25 customary units. All of these uoms are deprecated and replaced by correct uoms. the new uoms will consistently be like the old with the following replacement abbreviations: mol(g) to mol, mol(kg) to kmol, and mol(lbm) to lbmole. Also, the uom Grad (gigaradian) is deprecated, it being of little use, and being too easy to confuse with the angular measure, grad. POSC This document is released as a more comprehensive dictionary of POSC units of measure. It includes the following additions. 1. More units to meet the needs of various groups. 2. Use of SameUnit element to record an RP66 equivalent symbol for the POSC unit. 3. an additional element, DimensionalClass, to give the dimensonality of the unit. 4. More extensive use of the QuantityType, although the listing given is not to be considered complete. The document is backward compatible with previous version 1.0, with the following exceptions: a) DocumentInformation has a slightly different form. b) all elements are in the same namespace. inverse henry reluctance C2T2/L2M POSC 1/H per Kelvin volumetric thermal expansion linear thermal expansion 1/K POSC 1/K per kilogram per mass 1/M POSC 1/kg per metre per length wave number 1/L POSC 1/m per square metre per area 1/L2 POSC 1/m2 per cubic metre per volume 1/L3 POSC 1/m3 per Newton per force T2/LM POSC 1/N WITSML per Pascal bulk compressibility compressibility LT2/M POSC 1/Pa per second per time operations per time frequency 1/T POSC 1/s per Volt per electric potential CT3/L2M POSC 1/V ampere electric current magnetic potential difference magnetomotive force C POSC A The ampere is that constant current which, if maintained in two straight parallel conductors of infinite length, of negligible circular cross section, and placed 1 metre apart in vacuum,would produce between these conductors a force equal to 2 x 10**-7 newton per metre of length.
