What is ISO 80000-12 - Quantities and units for condensed matter about?

Multiple systems of quantities developed across the world over time. Unified systems can facilitate research and communication within the scientific community, doing away with the need for conversion factors.

ISO 80000 comprises a series of international standards introducing the International System of Quantities (ISQ). The guidelines of the ISO 80000 family of standards specify the use of physical quantities and units of measurement, along with the related formulas and units, in scientific and educational documents.

ISO 80000-12 guides you with names, symbols, definitions and units for quantities of condensed matter physics. Where appropriate, conversion factors are also given.
