In electric motors it is the Torque Constant, aka K-sub-T. This constant which depends on a number of factors involving motor geometry and constuction is actually the ratio of torque to current. It does not have a unit name AFAIK

An Ampere is 200 nanoNewtons per meter, so I think the answer is "meter."

Electromotive force divided by current = resistance (units of ohms).
