I have done it, and you have answered me post
_before_ send this one!

http://www.wolframalpha.com/input/?i=(4*pi%5E2+%2F+G)++in+
(kg+*day%5E2%2Fmeter%5E3+)

79.24 kg days^2/m^3 (kilogram days squared per meter cubed)


Most of the physical quantities aren't numbers,
but numbers with unit. And when you change unit,
you change numerical value of that thing that
stood before unit ;-)


When student get wrong number, he just done exercise
wrong. If he get wrong unit, or don't write unit at all,
propably he have no idea what he is doing.

So think one more time, are you sure tou want to write
a sentence like this:
"...using the constant 79.2216"
:-)
