C3D Pipe: Minimum Curve Radius Units

I’m getting more into the python and C3D API. I get around to trying to get the Minimum Curve Radius. The value in the Pipe Properties is 1.0m, the output is producing 39.3701 inches. Is there a way or a setting in CAD for the property to output metric instead of imperial? I’m guessing not because all object settings I look into is set to meters. Is it a case of it is what it is because that’s how the Program/API is written?
