The length of 1000 feet is 04.8 meters, or 333.333 yards. Furthermore, 1000 feet is a distance of 0.189 miles, or 0.1646 nautical miles, and is equivalent to 0.3048 kilometers.
Although the foot has been used since the times of Ancient Greece, in 1960 the term came to refer to the international meter, which is defined as a third of a yard or a distance of exactly 0.3048 meters. Thus, 1000 feet is equal to 1000 x 0.3048 = 304.8 meters. By definition, a foot is a third of a yard. Thus, 1000 x 1/3 = 333.333, when rounded to 3 decimal places. There are 1000 meters in a kilometer and 0.621 miles in a kilometer. To convert, divide 304.8 by 1,000 to equal 0.3048 kilometers, and multiply 0.3048 by 0.6214 to equal 0.189 miles.
