Dear MathGroup,
The LightYear conversion appears to be significantly incorrect in the Units
package.
Needs["Miscellaneous`Units`"]
Needs["Miscellaneous`PhysicalConstants`"]
{Convert[LightYear, Meter], Convert[1.0Year SpeedOfLight, Meter]}
{9.4605*^15*Meter, 9.454254955488*^15*Meter}
I believe that the second value is the correct value. If you agree, you can
correct the Miscellaneous`Units` package by searching for LightYear and
pasting in the correct value.
