Can the electric field strength of a wire simply be calculated using the voltage / length formula:
Electric Field Strength = Voltage Across Wire/ Length of Wire
I am asking about a wire with current running through it and not a charged wire.

$\begingroup$ To clarify, you're asking about a wire with current running through it, and not a charged wire (electrostatics)? $\endgroup$– BMSCommented Sep 26, 2014 at 18:28

Your method for evaluating the electric field assumes it is appropriate to model it as spatially constant within the wire since you're basically taking a spatial average. You'll have to decide wether or not this is accurate.
