In geography, latitude is a coordinate that specifies the north–south position of a point on the surface of the Earth or another celestial body. Latitude is given as an angle that ranges from –90° at the south pole to 90° at the north pole, with 0° at the Equator. Lines of constant latitude, or parallels, run east–west as circles parallel to the equator. Latitude and longitude are used together as a coordinat… WebFor this calculator, latitude is positive to the NORTH, and longitude is positive to the WEST of the prime meridian. Latitude and Longitude can be in deg/min/sec, or decimal … WebThen Earth Rotation Speed at our Equator: 1670 km/hr = 1037 mi/hr Note that our Earth has 24 Time Zones, so each zone is 1670 km or 1037 miles across at the Equator. The Equator is 0° latitude. Going north, latitude increases to 90° North (N) latitude at the North Pole. Going south, latitude increases to 90°South (S) latitude at the South Pole. dark side of gaming industry
