- I just posted about the conversion between miles and feet, and thought I might
- clear up any confusion I might have introduced.
-
- The normal units are foot and statute mile, and the conversion is 5280 feet/
- statute mile.
- There is also a US survey foot that is 1.000002 feet. This is not usually
- used unless you are a surveyor (I guess :^) ).
- There is also a measure of pressure known as a foot of water, and it is the
- pressure that one would find one foot below the surface of fresh water at sea
- level, and is 2989.07 Pa.
-
- As far as miles, the one normally used is the statute mile, as defined above.
- In addition the US survey mile is 5280 US survey feet.
- The nautical mile is used most often in nautical and aviation applications, and
- is 6076.1155 feet, or 1.150779 statute miles.
-
- Now a mile of water as pressure is... just kidding. :^)
-
- Those are all that I _now_ know about. I hope this helps
