A system for and noninvasively monitoring temperature within a body of a subject includes a transducer and an interface component. The transducer receives native temperature signals, which are electromagnetic signals. One or both of the transducer and the interface component convert the native temperature signals to a standard temperature signal. The interface unit may be configured to be coupled to a standard temperature signal-receiving apparatus, such as a standard vital signs monitor or a standard body temperature management system, which may recognize the standard temperature signal. Methods for noninvasively monitoring temperature, including receiving native temperature signals and converting the native temperature signals to a standard temperature signal, are also disclosed.
