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
