Mass of a body that is balanced by a standard mass under conventionally chosen conditions.
Notes:
- The International Organization of Legal Metrology recommends that the conventionally chosen conditions are: reference temperature, \(t_{\rm{ref}} = \pu{20 ^{\circ}C}\), density of air as a reference value, \(\rho_{0} = \pu{1.2 kg m−3}\); reference density of standard weight, \(\rho_{\rm{c}} = \pu{8000 kg m-3}\). In this case, the conventional mass is related to the mass (\(m\)) and density (\(\rho\)) of the object by \(m_{\rm{c}} = m \frac{1 - \rho_{0}/\rho}{1 - \rho_{0}/\rho_{\rm{c}}}\)
- The base unit of the quantity "conventional mass" is the kilogram.
