Tips & Best Practices
-
Remember that ampere/meter is an SI unit and oersted belongs to the cgs-emu system; conversions might vary in magnetic media other than free space
-
Use the tool to ensure consistent unit usage when comparing modern and historical magnetic data
-
Double-check conversion results when dealing with very small or large field values due to possible rounding effects
-
Apply the conversion formula consistently for reliable magnetic field strength translation
Limitations
-
The unit systems have different base assumptions, so conversions should be treated carefully when magnetic permeability varies from free space
-
Numerical precision may be affected by rounding, especially for extreme magnetic field values
Frequently Asked Questions
-
What is the relationship between ampere/meter and oersted?
-
One ampere per meter is equal to approximately 0.0125663706 oersted, linking the SI and cgs-emu units of magnetic field strength.
-
Why would I convert from A/m to Oe?
-
Conversion helps compare and use magnetic field data reported in different measurement systems, such as modern SI-based designs and older literature or instruments using oersted.
-
Are there any considerations when converting in different magnetic materials?
-
Yes, differences in magnetic permeability and unit systems mean conversions may not be straightforward outside free space, requiring careful interpretation.
Key Terminology
-
Ampere per meter [A/m]
-
The SI unit of magnetic field strength that measures the magnetizing field produced by currents or magnetized materials.

Oersted [Oe]
-
The cgs-emu unit of magnetic field strength representing the magnetizing force applied to a material.
-
Magnetic field strength (H)
-
A measure of the magnetizing field intensity in a material, quantified in units such as A/m or Oe.
-
Magnetic permeability
-
A property of materials that affects the relationship between magnetic field strength and magnetic flux density, important in unit conversions.
