Fun problems

Here are some unit problems to play with:

1.  Create a factor to convert from m/s to light-years (LY) per millennium.  1 LY = 9.4607 x 10^12 km.

2.  Create your own conversion factor - m/s to something else interesting.

3.  How long is a micro-century?  Give your answer in units that are appropriate.   Also, micro equals 1 millionth.

4.  A good problem to think about.  If we gathered ALL of the people in the world together for the world's largest party, how large a social hall would we need to build?  Think about how to calculate this, and try it.  You'll have to make a couple of assumptions, of course.
