A very useful use of Google is to type something like the following into the
seach field:
"1 lightyear in cubits", and you get
1 light year = 2.06923193 ?? 10^16 cubits, see:
http://www.google.com/search?hl=en&ie=UTF-8&oe=UTF-8&q=1+light+year+in+cubits&btnG=Google+Search
You can even do cool stuff like
"60 mph in furlongs/fortnight" and get
161 280 furlongs per fortnight, see:
http://www.google.com/search?hl=en&lr=&ie=UTF-8&oe=UTF-8&q=60+mph+in+furlongs+per+fortnight&btnG=Google+Search
And perhaps the coolest thing:
type "e^(i*pi)" in the search and it'll return -1, see the following URL
http://www.google.com/search?hl=en&lr=&ie=UTF-8&oe=UTF-8&q=e%5E%28i+*+pi%29&btnG=Google+Search
Further proof that Google is the coolest website on the planet, IMHO.

OK,
I'll bite:
From a paper by Stanek and Garnavich, using parallax distance =
measurements to "Red Clump" giants in M31 (hi AJ), a mean distance of
784 kpc plus/minus ~2 percent is derived. So I'll take 784 kpc (784000 =
parsecs) as "gospel."
So we have:
1 parsec =3D 3.08568025 =D7 10E16 meters
1 cubit =3D 0.4572 meters
cubits/parsec =3D 3.08568025 =D7 10E16 meters / 0.4572 meters =3D =
6.74908191164 x 10E16
Finally:
6.74908191164 x 10E16 cubits/parsec * 784000 parsec=3D 5.29128021872 x =
10E22 cubits
That's a pretty long walk . . .
