What Is This Tool?
This converter facilitates the transformation of magnetic field strength values from oersted, a cgs unit used historically and in some legacy contexts, to kiloampere per meter, a modern SI unit common in magnetic measurements and engineering. It supports understanding and conversion across unit systems for various scientific and industrial purposes.
How to Use This Tool?
-
Enter the magnetic field strength value in oersted (Oe).
-
Select oersted as the input unit and kiloampere per meter (kA/m) as the output unit.
-
Click the convert button to get the equivalent value in kiloampere per meter.
-
Use the result in magnetics analysis, design calculations, or to compare with SI-based data.
Key Features
-
Converts magnetic field strength between oersted and kiloampere per meter.
-
Supports magnetics research, permanent magnet manufacturing, and materials testing needs.
-
Browser-based and user-friendly interface for quick conversions.
-

Examples
-
10 Oe equals 0.795774715 kA/m by multiplying 10 by the conversion factor 0.0795774715.
-
50 Oe is converted to 3.978873575 kA/m using the same method.
Common Use Cases
-
Converting magnetic field strengths from older cgs-based literature for modern SI analysis.
-
Specifying coercive field and operating points on hysteresis curves in magnetic materials.
-
Designing electromagnets and magnetic circuits requiring magnetizing field values in SI units.
-
Reporting magnetizing fields in testing and characterization of magnetic materials.
Tips & Best Practices
-
Ensure you understand the difference between cgs and SI units before converting.
-
Use the exact conversion factor provided for accurate unit translation.
-
Check legacy datasheets carefully when interpreting oersted values due to system differences.
-
Be mindful of unit scaling, as kiloampere per meter is a large SI unit.
Limitations
-
Oersted is used primarily in the cgs-emu system and may cause confusion without proper context.
-
Careful interpretation is needed when translating legacy measurements to SI units.
-
Kiloampere per meter units require appropriate scaling to maintain numerical clarity.
