Linear Current Density Converter

Convert between linear current density units: ampere per meter (A/m), ampere per centimeter, milliampere per meter, and more.

What this tool does

Convert between linear current density units: ampere per meter (A/m), ampere per centimeter, milliampere per meter, and more. Type an amount in amperes per meter, choose the units, and the tool converts it to amperes per centimeter. It offers 7 magnetic field strength units and also shows the same amount in the others.

Inputs

  • Value: A number.
  • From: Choose one: Ampere per meter, Ampere per centimeter, Ampere per millimeter, Milliampere per meter, Microampere per meter, Kiloampere per meter, Ampere per inch. Starts as Ampere per meter.
  • To: Choose one of the same 7 units as "From". Starts as Ampere per centimeter.

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 amperes per meter to amperes per centimeter:

  • 1 A/m = 0.01 A/cm
  • 5 A/m = 0.05 A/cm
  • 10 A/m = 0.1 A/cm
  • 50 A/m = 0.5 A/cm
  • 100 A/m = 1 A/cm

Multiply the number of amperes per meter by 0.01 to get amperes per centimeter. Both units are exact definitions, so 0.01 is the exact factor: 1 A/m = 0.01 A/cm.

Sources: Ampere per meter: SI Brochure, 9th edition (2019). Ampere per centimeter: exact by definition.

Limitations

  • Converts the unit only. It does not work out current density from a current and a length.
  • Linear current density and magnetic field strength are measured in the same units, so the unit list on this page is headed magnetic field strength.

FAQs

Q: How do I convert A/m to A/cm?
A: Enter the value, choose A/m as the From unit and A/cm 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 linear current density the same as magnetic field strength?
A: They share the same unit, amperes per meter, and the same conversion factors. Linear current density is the current per unit width of a conducting sheet, or the ampere-turns per unit length of a winding such as a solenoid.
