Thanks to @Michael-Kowata for this pull request. Could you please help with the following:

• Could you make the title of the pull request reflect that it is for test case LG6.
• The box in the description is not checked for all contributors signing the CLA. The description should list all the authors names too. I also don't see a record of signed CLAs by the people I could determine contributed (let me know if my records are off).
• Please do the other items indicated for the description (also on the developer help pages).
• I did quickly look at the code and it has units and conversions arrays below the test. These are not needed as they are part of the test code. I will do a full reading once all items are in place.

Let me know if you need anything.

Hey Huss, I apologize for the previous pull request. It's been updated now.

Everything but the CLA looks good. According to my records, @Michael-Kowata @Kyongsu729 & @mflores6140 have not agreed to the CLA (see link in description). Please agree or let me know that my records are wrong.

We filled out the CLA form. Let us know if there is anything else we need to do.
