The unit for magnetic moment is not a base unit in the International System of Units (SI) and it can be represented in more than one way. For example, in the current loop definition, the area is measured in square meters and formula_6 is measured in amperes, so the magnetic moment is measured in ampere–square meters (formula_32). In the equation for torque on a moment, the torque is measured in Newton.meters and the magnetic field in tesla, so the moment is measured in N.m per Tesla (formula_33). These two representations are equivalent:
