David Wheeler updated OFFICE-3492:
-----------------------------------
Proposal:
Here are the proposed changes to CONVERT. (Editor: This includes citations for some non-obvious values, if you need to change the citation format feel free.)
In row "ly" (light-year), append this to the Description:
, exactly (299792458 m/s) (3600 s/hr) (24 hr/day) (365.25 day).
(Source: International Astronomical Union (IAU),
"Measuring the Universe: The IAU and astronomical units", http://www.iau.org/public/measuring/).
In row "bushel", append this to the Description:
, exactly 2150.42 cubic international inches.
(Source:
National Institute of Standards and Technology (NIST),
Appendix C of NIST Handbook 44, "Specifications, Tolerances, and Other Technical Requirements for Weighing and Measuring Devices",

** NOTE: THIS PROPOSAL WILL BE EDITED FURTHER, BUT I WANTED EVERYONE TO SEE WHERE I'M GOING.
BELOW ARE NOTES, AND NOT YET PART OF THE UPDATED PROPOSAL. **
[We will add a statement making it clear that NOT all values are exact.]
"pc": 1 pc = 3.085677581E+16 m
1 m = 3.24077928996043E-17 pc
"HP": 1 HP = 745.699871582 W
1 W = 0.00134102208959551 HP
"PS": 1 PS = 735.49875 W
1 W = 0.0013596216173039 PS
(METAS lists this as CV instead of PS)
Conversion factors according to OOo implementation:
"uk_gal": 1 L = 0.219969461940207 uk_gal
"uk_qt": 1 L = 0.87987784776083 uk_qt (1 uk_qt = 1/4 uk_gal)
"uk_pt": 1 L = 1.75975569552166 uk_pt (1 uk_pt = 1/8 uk_gal)
"pond": 1 N = 101.9716 pond

"ly": The exact value of one light year is (299792458 m/s) (3600 s/hr) (24 hr/day) (365.25 day/year)
1 bushel = 2150.42 cubic inches exactly.
NOTE FROM WHEELER: I don't think the ones below are exact, and thus need work:
"pc": 1 pc = 3.085677581E+16 m
1 m = 3.24077928996043E-17 pc
"HP": 1 HP = 745.699871582 W
1 W = 0.00134102208959551 HP
"PS": 1 PS = 735.49875 W
1 W = 0.0013596216173039 PS
(METAS lists this as CV instead of PS)
Conversion factors according to OOo implementation:
"uk_gal": 1 L = 0.219969461940207 uk_gal
"uk_qt": 1 L = 0.87987784776083 uk_qt (1 uk_qt = 1/4 uk_gal)
"uk_pt": 1 L = 1.75975569552166 uk_pt (1 uk_pt = 1/8 uk_gal)
"pond": 1 N = 101.9716 pond

> Project: OASIS Open Document Format for Office Applications (OpenDocument) TC
> Issue Type: Bug

> There are still a number of units that are undefined and cannot be implemented as described. These should all be defined with numbers.
> "ly" * Light-year, the distance light travels, in a vacuum, in a Julian year of 365.25 days
> "parsec" or "pc" * Distance from sun to a point having heliocentric parallax of one second (used for stellar distance)*
> "PS" Pferdestärke (German "horse strength", close but not identical to "HP")
> "bushel" U.S. bushel (not Imperial bushel), interpreted as volume
> "uk_gal" U.K. / Imperial gallon
> "uk_qt" U.K. / Imperial quart
> Also, for "pond", there is a need to specify what to use for acceleration due to gravity
> "pond" * Pond, gravitational force on a mass of one gram
