In the same sense that Newtons (N) are the unit for measuring gravitational force, is there a unit for measuring electromagnetic force and if so what is it and what symbol denotes it? Thank you for your help and time!

Force is force. The Newton is an appropriate unit regardless of whether the force is from gravity or any other source.

The force from an electric field is proportional to charge. This means that an appropriate unit for expressing field strength is Newtons per coulomb or equivalently, Volts per meter.

This is analogous to the way in which gravitational field strength is measured. Those units are Newton's per kilogram or equivalently (because the kilograms cancel out), meters per second squared.
