Electric field #vecE# is defined as the electric force #vecF# per unit charge. Alternatively, force experienced by a very small test charge #q# when placed in electric field #vecE#

#vecE = vecF/q#
The direction of the field is the direction of the force it would exert on a positive test charge.

As such units of Electric Field are newtons per coulomb, #"N⋅C"^-1# or equivalently, volts per metre #"V⋅m"^-1#
