Answer 2

1 inch = 2.54 centimeters

An inch (plural: inches; symbol or abbreviation: in or, sometimes, ″ - a double prime) is the name of a unit of length in a number of different systems, including English units, Imperial units, and United States customary units. Its size can vary from system to system. There are 36 inches in a yard and 12 inches in a foot. A corresponding unit of area is the square inch and a corresponding unit of volume is the cubic inch.

The inch is the virtually universal unit of measurement in the United States, and is very commonly used in Canada and the United Kingdom. In the US and commonly in the UK and Canada, personal heights are expressed in feet and inches by people of all ages. In Canada, personal heights are shown in metric units on official documents such as a person's driver's license.

In 1958 the United States and countries of the Commonwealth of Nations defined the length of the international yard to be precisely 0.9144 metres. Consequently, the international inch is defined to be equal to 25.4 millimetres.

The international standard symbol for inch is in (see ISO 31-1, Annex A). In some cases, the inch is denoted by a double prime, which is often approximated by double quotes, and the foot by a prime, which is often approximated by an apostrophe. For example, 10 feet 9 inches is denoted by 10′9″.

Answer 3

Inch comes from the Old English (say 1000AD) 'ynce', which came from the Roman 'uncia' meaning 'one-twelth'. So the word essentially is not - originally - an indicator of a 'measure' but an indicator of a proportion of a measure, in this case of 'a foot'.

The 'foot' (the measure), comes from the the length of the foot (the thing at the end of your leg).
