The inch is usually the universal unit of measurement in the United States, and is widely used in the United Kingdom, and Canada, despite the introduction of metric to the latter two in the 1960s and 1970s, respectively.
The Pacific Ocean meets the Atlantic south of South  America at Cape Horn, and over the North Pole (the ice-cap is only  floating sea-ice). In reality, the Pacific and Atlanâ¦tic Oceans only  exist as separate oceans because we agree to draw an imaginary line  that separates and divides them.
The Atlantic ocean is second in size to the Pacific. It occupies an area of about 106,400,000 square kilometres (41,100,000 sq mi). The volume of the Atlantic with its adjacent seas is 354,700,000 cubic kilometers. The average depth of the Atlantic with its adjacent seas, is 3,339 metres (1,826 fathoms; 10,955 ft).
