Units and Measurements

The units available in Scientific Notebook include units from the System of International Units (SI units), an internationally agreed upon system of coherent units that is now in use for all scientific and most technological purposes in many countries. SI units are of three kinds: the base, supplementary, and derived units. There are seven base units for the seven dimensionally independent physical quantities: length, mass, time, electric current, thermodynamic temperature, amount of substance, and luminous intensity. Units from other commonly used systems are also available in Scientific Notebook.
