 ## References for Unit definitions
 
 - [UDUNITS-2](https://github.com/Unidata/UDUNITS-2) The UDUNITS package supports units of physical quantities. Its C library provides for arithmetic manipulation of units and for conversion of numeric values between compatible units. The package contains an extensive unit database, which is in XML format and user-extendable. The package also contains a command-line utility for investigating units and converting values. Some of the unit definition files are used to test the library to ensure compatibility with the definitions in this library. Some of the definitions files are included. UDUNITS-2 is licensed with a [BSD-3-clause](https://github.com/Unidata/UDUNITS-2/blob/master/COPYRIGHT) with an additional clause revoking the license on allegations of patent infringement. No code from UDUNITS-2 is used, only the unit definitions files.
 - [ucum-lhc](https://github.com/lhncbc/ucum-lhc) This is the LHC implementation of validation and conversion services based on the [Unified Code for Units of Measure](http://unitsofmeasure.org/) (UCUM) code system created by the Regenstrief Institute, Inc. The repository is licensed under a [BSD](https://github.com/lhncbc/ucum-lhc/blob/master/LICENSE.md) license. No code is used in units, but the unit definition files are used for testing purposes and some of the JSON files are included in the repository.
 - [google unit conversions](https://support.google.com/websearch/answer/3284611?hl=en#unitconverter) Google unit conversion support was examined to provide additional unit strings and some conversion values.

 ### cmake scripts
 
 Several CMake scripts came from other sources and were either used or modified for use in HELICS.
 
 - Lars Bilke [CodeCoverage.cmake](https://github.com/bilke/cmake-modules/blob/master/CodeCoverage.cmake)
 - [HELICS](https://github.com/GMLC-TDC/HELICS) Some of the code CMake and build scripts and a few of the docker images used for testing are maintained through the HELICS library. HELICS also uses the units library for unit translations.

 ==================
 The Python wrapper for the units library is a simplified version of the library.  It is focused on the string operations of the library and conversions between units and measurements.
