International System of Quantities (ISQ)

The International System of Quantities (ISQ) consists of the quantities used in physics and in modern science in general, starting with basic quantities such as:

  • length
  • mass
  • time
  • electric current
  • thermodynamic temperature
  • amount of substance
  • luminous intensity

and the relationships between those quantities. This system underlies the International System of Units (SI) but does not itself determine the units of measurement used for the quantities. It is inherently incomplete because the number of quantities is potentially infinite.
