David Wheeler commented on OFFICE-3492:
----------------------------------------
We should only include exact values in the specification. That way, no matter what numeric model is used, the result can be accurate within the numeric model.
I don't think some of these values in the proposal are exact. Can you confirm that they are all exact? In particular, the reciprocal of a value is almost never exact in practice. In addition, I don't think you need to give the conversion directly to SI. As long as you give the exact conversion to something that CAN be converted to SI, I think that's fine.
Thus, we should NOT state that "bushel": 1 L = 0.0283775933 bushel, because I believe that is not exact.
Instead, we should just state that:
1 bushel = 2150.42 cubic inch
Implementors can easily use that information to figure out the rest.
Also, regarding "The standard acceleration of gravity in free fall is 9.80665 m/s2.", yes, we do need to state this somewhere. The acceleration of gravity on Earth actually varies depending on where you are on the Earth. So for a "standard acceleration" there could be many possible values, and we need to specify one.

> 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
