  "definition": "Test Process that sources a conventional value of the result of weighing a body in air equals the mass of a standard that balances this body under the following conventionally chosen conditions: ambient temperature 20 \u00b0C air density 1.2 mg/cm\u00b3 mass density 8.000 g/cm\u00b3 Conventional mass has the same unit as mass (the kilogram), because the multiplication of a mass by a dimensionless quantity defines its values. Labs typically measure mass and correct the results from actual to conventional conditions. \u201cApparent Mass versus 8.0 g/cm\u00b3\u201d formerly equated to conventional mass in the United States.
