The interface traffic values are either in kbit/s or b/s. Is there a way to convert this to Mbps or KB/s when displaying via UMP? I noticed I can realtime monitor in those values, but it doesn't look like a can convert them for display purposes.
You can convert the value when displaying in Performance Report Designer. Add the values to the graph, then click the "Configure" icon in the top left and choose "Scale." This will allow you to put in a multiplier to convert the unit. For example, a multiplier of 0.0009765625 (1/1024) will convert from B to KB or KB to MB.
