	If the British engineering units system is the base unit system, the COMSOL Multiphysics software constructs derived units from the applicable SI base units and the units listed in Table 3-12 and Table 3-13. This means, for example, that the unit for voltage displayed in the physics interface is lbf·ft/As rather than V (volt). In a text field that expects a voltage as input, you need to use the unit syntax when entering a numerical value (for example, 10[V]).
