Electricity and magnetism are related but not in
the way you have suggested. You can not convert
Gausses into Coulombs or vise versa.

Gauss is the unit of magnetic field intensity
which is usually denoted by B. As its name indicated,
it represents the strength of the magnetic field.

If you want to convert magnetism into electricity,
you need a changing magnetic field and a coil.
The magnetic fields penetrating the cross-section
of the coil is called magnetic flux, which is
Phi = B * A, where B is the magnetic field intensity,
A is the area of the cross-section of the coil.
Suppose B is changing with time and its changing
rate (its derivative to time) is dB/dt, you will
get a voltage source in the coil with the voltage
as V = dB/dt * A. Suppose the resistance of the coil
is R, you will get a current flowing in it, which
is I = dB/dt * A /R. Its unit is Column/second, which
I think is the most nearest thing to you have suggested.
