What Is This Tool?
This converter transforms magnetic field strength values from oersted (Oe), commonly used in older datasheets and the cgs system, into ampere per meter (A/m), the modern SI unit. It supports scientists and engineers in translating measurements for compatibility with current standards.
How to Use This Tool?
- Input the magnetic field strength value in oersted [Oe].
- Select oersted [Oe] as the input unit and ampere/meter [A/m] as the output unit.
- Click the convert button to get the value in ampere per meter.
- Review the converted result for use in SI-based calculations.
Key Features
- Converts magnetic field strength units from Oe to A/m accurately.
- Uses established conversion rates between cgs and SI units.
- Supports magnetic research, engineering, and data interpretation.
- Browser-based and easy to use without installation.
Examples
- 2 Oe converts to approximately 159.1549 A/m.
- 0.5 Oe converts to about 39.7887 A/m.
Common Use Cases
- Specifying coercive field and magnet parameters from older datasheets.
- Plotting hysteresis loops with magnetic field strength in Oe and flux density in gauss.
- Converting legacy data and equipment outputs from cgs to SI units.
- Designing electromagnets and solenoids using SI magnetic field units.
- Analyzing magnetic circuits and determining core operating points.
Tips & Best Practices
- Always double-check the original unit before conversion.
- Use this conversion when working with older literature or cgs-based devices.
- Remember that magnetic material properties influence related measurements beyond H field values.
- Interpret historical Oe data carefully considering cgs and SI system differences.
Limitations
- 1 Oe corresponds to magnetic field strength in free space; additional factors apply within materials.
- Conversions do not account for magnetic permeability or flux density variations.
- Interpreting older data requires awareness of differing unit conventions and definitions.
Frequently Asked Questions
- What does 1 Oe equal in ampere per meter?
- 1 Oe is equal to approximately 79.5775 A/m according to the established conversion.
- Why do I need to convert from Oe to A/m?
- Conversion is necessary to translate magnetic field measurements from the cgs system into the SI system used in many modern scientific and engineering applications.
- Can I use Oe values directly in SI-based calculations?
- No, values in Oe must be converted to A/m for proper use with SI units and compatibility with contemporary standards.
Key Terminology
- Oersted (Oe)
- The cgs-emu unit of magnetic field strength representing the magnetizing force applied to a material.
- Ampere per meter (A/m)
- The SI unit of magnetic field strength quantifying the magnetizing field from currents or magnetized materials.
- Magnetic Field Strength (H)
- A measure of the intensity of the magnetizing field applied to a material, expressed in units such as Oe or A/m.
