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. How long is a nano-year. Nano is a billionth.
5. Roughly, what is the growth rate of your hair in m/s?
6. What is your average speed on the way to school - in miles per hour (and m/s)?
