Electric Field Strength Converter

Convert between electric field strength units: volt per meter (V/m), kilovolt per meter (kV/m), volt per centimeter, newton per coulomb, and more.

What this tool does

Convert between electric field strength units: volt per meter (V/m), kilovolt per meter (kV/m), volt per centimeter, newton per coulomb, and more. Type an amount in volts per meter, choose the units, and the tool converts it to kilovolts per meter. It offers 9 electric field strength units and also shows the same amount in the others.

Inputs

  • Value: A number.
  • From: Choose one from 9 options, including Volt per meter, Kilovolt per meter, Megavolt per meter, Volt per centimeter, Volt per millimeter, Millivolt per meter. Starts as Volt per meter.
  • To: Choose one of the same 9 units as "From". Starts as Kilovolt per meter.

How to use

  1. Enter the amount you want to convert.
  2. Choose the unit to convert from and the unit to convert to.
  3. Read the result: the converted amount and the same amount in the other units. It appears once every required field has a valid value.

Worked examples

Conversions from volts per meter to kilovolts per meter:

  • 1 V/m = 0.001 kV/m
  • 5 V/m = 0.005 kV/m
  • 10 V/m = 0.01 kV/m
  • 50 V/m = 0.05 kV/m
  • 100 V/m = 0.1 kV/m

Multiply the number of volts per meter by 0.001 to get kilovolts per meter. Both units are exact definitions, so 0.001 is the exact factor: 1 V/m = 0.001 kV/m.

Limitations

  • Converts electric field strength only. It does not work out a field from a voltage and a gap.

FAQs

Q: How do I convert V/m to kV/m?
A: Enter the value, choose V/m as the From unit and kV/m as the To unit. The result and the other units in the list update immediately. To go the other way, swap the two units.
Q: Is a newton per coulomb the same as a volt per meter?
A: Yes. They are two ways to write the same unit of electric field strength, so the conversion between them is one to one.
Q: What is a statvolt per centimeter?
A: It is the CGS electrostatic unit of electric field strength. One statvolt is 299.792458 volts, so one statvolt per centimeter is 29,979.2458 volts per meter.
