Simple method is passing the unknown current value to the known resistor value to calculate the voltage and convert it back to current using the reverse formula to find out the unknown current. Use some precision resistors to find out the value
A transimpedance amp only measures current to ground (it must be in series between the current being measured and ground).
Is that what you want?
Normally a transimpedance amp is used to measure small currents from a signal device, such as a photo-diode, where you want zero voltage drop from the measuring circuit.
What is your application?
