The ISO 217:2013 standard defines the RA and SRA paper formats. These paper series are untrimmed raw paper. RA stands for raw format A and SRA stands for supplementary raw format A. The RA and SRA formats are slightly larger than the corresponding A series formats. This allows bleed (ink to the edge) on printed material that will be later cut down to size. These paper sheets will after printing and binding be cut to match the A format.
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.
