• Iso is the stem of the Latin transliteration of the Greek word ίσος (ísos, meaning "equal"). The "iso-" prefix in English derives from this and means equality or similarity.
• An isogram or an isorithm in cartography is a contour line, a reference to the fact that they connect points of equality. An isarithm is a contour map. An isobar is a curve on a contour map representing points on a surface that have the same atmospheric pressure.
• ISO is the International Organization for Standardization, a global federation of over a hundred national standards bodies with central secretariat in Geneva, Switzerland. The name ISO is derived from ίσος (see above) and is not an acronym for the organization's name in any of its working languages, though it is conventionally written in all capitals.
• An ISO standard, an international standard published by the ISO. Although more than 15000 ISO standards have been published so far, each identified by a document number, the term "ISO" is in some fields commonly used just on its own as a shortname for something defined in one of these specifications. For example:
• The ISO number in photography is the measure of film speed, or the sensitivity of photographic film to light exposure. It is defined in international standard ISO 5800.
