Off the top of my head, again:

1000 thou = 1 inch

4 inches = 1 hand

3 hands = 1 foot

3 feet = 1 yard

220 yards = 1 furlong

8 furlongs = 1 mile

1 furlong by 66 feet = 1 acre.

NOTE: I missed chains!

22 yards = 1 chain
10 chains = 1 furlong
1 chain = cricket wicket
1 furlong x 1 chain = 1 acre.

And of course,

10 millimeters = 1 centimeter

100 centimeters = 1 meter

1000 meters = 1 kilometer

1000 kilometers = 1 megameter

and so on, and I think that something like 10 petameters is a light year.
