I'm using the 1D Rectangular to Polar VI and would like to know the output magnitude units.

What is the magnitude output unit expressed in? VRMS, DB, etc...?The other output from the 1D Rectangular to Polar VI, phase, is expressed in radians.

Well it all depends on what you are inputting to the conversion function. The definition is, given two input values a and b (that often represent a complex numbe a+j*b), magnitude = sqrt(a^2 + b^2). If a+j*b represent the complex "amplitude" of a spectrum, then the result will also be an amplitude (V). But most likely (the normal case), you are inputting a complex magnitude that will be returned as a magnitude in Vrms.

The 1D Rectangular to Polar VI only accepts inputs without units, it seems.

This is just a geometric transformation and the magnitude output should thus get the same "units" as the x and y inputs originally had (before stripping the units off).
