Description  There are SI units of measure for the units of measure. STEP (ISO/DIS 10303-41. S96ff) is supported with regard to SI units by seven basic units (length, mass, time, electric_current, thermodynamic_temperature, amount_of_substance, luminous_intensity). These basic units are realized by means of attributes.
