The United States, Canada, and the Philippines primarily use a different system of paper sizes compared to the rest of the world. The current standard sizes are unique to those countries, although due to the size of the North American market and proliferation of both software and printing hardware from the region, other parts of the world have become increasingly familiar with these sizes (though not necessarily the paper itself). Some traditional North American inch-based sizes differ from the Imperial British sizes.
Letter, Legal and Ledger/Tabloid are by far the most commonly used of these for everyday activities, and the only ones included in Cascading Style Sheets (CSS). US paper sizes are currently standard in the United States and are the most commonly used formats at least in the Philippines, most of Mesoamerica and Chile. The latter use US Letter, but their Legal size is one inch shorter than its US equivalent.
Unit of measurement
A Unit of measurement is a definite magnitude of a value, defined and adopted by convention that is used as a standard for measurement of the same kind of value. Any other quantity of that kind can be expressed as a multiple of the unit of measurement.
mm stands for millimeter (American spelling) or millimetre (SI spelling) is the size of the unit of length in the metric system, that is the basis of the length measurement. 1 mm is equal to 0.1 cm.
cm stand for centimetre (international spelling as used by the International Bureau of Weights and Measures) or centimeter (American spelling) is a unit of length in the metric system, equal to one hundredth of a meter. cm being the International System of Units prefix for a factor of one per a hundred. cm is the base unit of length for cgs (centimetre–gram–second) system of units.
Inch (plural: inches, abbreviation: in or ″) is a unit of length in the imperial and United States customary systems of measurement, now formally equal to one per thirty six yard but usually understood as one per twelve of a foot. Derived from the Roman uncia, “inch” is also sometimes used to translate related units in other measurement systems. Traditional standards for the exact length of an inch have varied in the past, but since the adoption of the international yard during the 1950s and 1960s it has been based on the metric system and reckoned as exactly 2.54 cm.
