Last, multiply the original expression of the physical value by the fraction, called a conversion factor, to obtain the same physical value expressed in terms of a different unit. Note: since valid conversion factors are dimensionless and have a numerical value of one , multiplying any physical quantity by such a conversion factor (which is 1 ...
A light-year is the distance light travels in one Julian year, around 9461 billion kilometres, 5879 billion miles, or 0.3066 parsecs. In round figures, a light year is nearly 10 trillion kilometres or nearly 6 trillion miles. Proxima Centauri, the closest star to Earth after the Sun, is around 4.2 light-years away. [89]
Various historic miles and leagues from an 1848 German textbook, given in feet, metres, and fractions of a "degree of meridian" The German mile (Meile) was 24,000 German feet. The standardised Austrian mile used in southern Germany and the Austrian Empire was 7.586 km; the Prussian mile used in northern Germany was 7.5325 km.
A DMS value is converted to decimal degrees using the formula: = + + For instance, the decimal degree representation for 38° 53′ 23″ N, 77° 00′ 32″ W (the location of the United States Capitol) is 38.8897°, -77.0089°
kilometre (km) or kilometer is a metric unit used, outside the US, to measure the length of a journey; the international statute mile (mi) is used in the US; 1 mi = 1.609344 km; nautical mile is rarely used to derive units of transportation quantity.
= 6,371.009 kilometers = 3,958.761 statute miles = 3,440.069 nautical miles. = Distance between the two points, as measured along the surface of the Earth and in the same units as the value used for radius unless specified otherwise.

The destinations listed can range from a short distance away, such as a few miles or kilometers, to long distances away, from several hundred or even thousands of miles or kilometers away. Unlike most road signs, mileage signs remain roughly consistent throughout the world, with the only differences being background colors on signs and the ...
