David Wheeler  commented on OFFICE-3492:
----------------------------------------

We discussed this comment on 2010-11-02 (see the meeting minutes).  Wheeler will pick this up and try to improve it, per the meeting minutes.

In particular, a statement will be added (per Rob Weir) making it clear that some values aren't exact.

The previous proposal was as follows:

***

Conversion factors according to
http://www.metas.ch/metasweb/Themen/Masseinheiten/calculation/en_calculation_frame_umrechnungen.html

"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

***

Wheeler will create a new proposal and put that in the comment field.

> 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"	PferdestÃ¤rke (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
