Rules for assigning units
The associated units are determined for each numerical attribute, if applicable. Specification in different units is not allowed. Units should be assigned according to SI units. If other units have gained acceptance in engineering practice, they will be accepted; e.g., "revolutions per minute."
The list of possible units can be viewed in the REXS database.
