KM
The Kilometre (Km). 1/299,792,458th of a second.
Kilometre is 1 / 10,000 of the average distance on the Earth between the Equator and either Pole.
DISTANCE ON THE EARTH
NAVIGATION
SM
Is defined in a Royal Statute of Queen Elizabeth the first (of England) and is 5280 feet .
DISTANCE ON THE EARTH
NAVIGATION
Nm
One minute of latitude = 1 Nautical mile
One degree of latitude=60 minutes = 60 Nm
But
One minute of longitude = 1 nm at the equator only
Great Circle arcs
DISTANCE ON THE EARTH
NAVIGATION
Nm• One degree of longitude 30 = (360 x 60) > 21600 x cos 30 = 18706
• 18706/ 360 = 52
• One degree of longitude 30 = 52 Great Circle arcs Nm
DISTANCE ON THE EARTH
One degree of longitude 60 = (360 x 60) > 21600 x cos 60 = 10800
10800/ 360 = 30
One degree of longitude 60 = 30 Great Circle arcs Nm
