value and unit of dipole moment

Dear All,
I want to get the value of the dipole moment of a molecule. I used the following perl script:

my \$length = \$setMolecule->DipoleMoment->Length;

Is this length in the unit of e-A? Or if I was wrong, is there another way to get the value of the dipole moment?

Thank you!

All the best,
Jingjing
