Best answer
The SI unit of mutual inductance is the henry (H), which is the same as the unit for inductance.

Mutual inductance (denoted as M) measures the ability of one coil or conductor to induce an electromotive force (EMF) in another nearby coil due to a changing current. It is defined as the ratio of the induced voltage in one coil to the rate of change of current in the other coil.

1 henry (H) is equal to 1 volt-second per ampere (V·s/A).
