The 60th parallel north is a circle of latitude that is 60 degrees north of Earth's equator. It crosses Europe , Asia , the Pacific Ocean , North America , and the Atlantic Ocean . Although it lies approximately twice as far away from the Equator as from the North Pole , the 60th parallel is half as long as the Equator line, due to the cosine ...
The 45th parallel north is often called the halfway point between the equator and the North Pole, but the true halfway point is 16.0 km (9.9 mi) north of it (approximately between 45°08'36" and 45°08'37") because Earth is an oblate spheroid; that is, it bulges at the equator and is flattened at the poles.

The 36th parallel north is a circle of latitude that is 36 degrees north of the Earth's equatorial plane. It crosses Africa, the Mediterranean Sea, Asia, the Pacific Ocean, North America and the Atlantic Ocean. In the ancient Mediterranean world, its role for navigation and geography was similar to that played by the Equator today. [1]
The two surveys were roughly two miles apart, creating a thin area claimed by both states. While the border was intended to follow 36°30′ north, early surveying errors caused it to veer north of that, reaching a distance of almost ten miles off by the time it reached the Tennessee River.

The metre was defined as one ten-millionth of the shortest distance from the North Pole to the equator passing through Paris, assuming an Earth's flattening of 1/334. The committee extrapolated from Delambre and Méchain's survey the distance from the North Pole to the Equator which was 5 130 740 toises.
The 50th parallel north is a circle of latitude that is 50 degrees north of the Earth's equatorial plane. It crosses Europe , Asia , the Pacific Ocean , North America , and the Atlantic Ocean . At this latitude the sun is visible for 16 hours, 22 minutes during the summer solstice and 8 hours, 4 minutes during the winter solstice . [ 1 ]
The 46th parallel north is a circle of latitude that is 46 degrees north of the Earth's equatorial plane. It crosses Europe , Asia , the Pacific Ocean , North America , and the Atlantic Ocean . At this latitude the sun is visible for 15 hours, 45 minutes during the summer solstice and 8 hours, 38 minutes during the winter solstice .
An early determination was that between Potsdam and The Brocken in Germany, a distance of about 100 miles (160 km), in 1906. [114] In 1911 the French determined the difference of longitude between Paris and Bizerte in Tunisia, a distance of 920 miles (1,480 km), and in 1913–14 a transatlantic determination was made between Paris and Washington .
