About the electric field strength converter

Electric field strength quantifies the force per unit charge experienced at a point in space, with SI units of volts per meter (V/m), equivalent to newtons per coulomb (N/C). It governs how strongly a field accelerates charges and whether a dielectric will break down — air arcs at roughly 3 × 10⁶ V/m. Insulation engineers, antenna designers, and capacitor makers all work in V/m or its imperial cousin V/in.

Frequently asked questions

  • Is V/m the same as N/C?

    Yes. The two units are dimensionally identical: 1 V/m = 1 N/C. Choose whichever is more convenient for the problem.

  • What is the breakdown field of air?

    About 3 MV/m (3 × 10⁶ V/m) at sea-level pressure. Above that, air ionizes and you get arcing.
