See http://www.onlineconversion.com/speed_all.htm
That site has many conversions too. Now I just have to figure out how to get
online while flying. ;-)

Normally my airspeed indicator and GPS are in MPH. I do the conversion, if
necessary, on the ground while planning the flight.

One good place to check out formulas and such is google.

Example: type in google search bar:

1 mph in knots

it will come back with 1 mph = 0.868976242 knots
