How to Convert Amperes per Meter to Oersteds
To convert amperes per meter to oersteds, multiply the magnetic field strength by the following conversion ratio: 0.0125664 oersteds/ampere per meter.
Since one ampere per meter is equal to 0.0125664 oersteds, you can use this simple formula to convert:
The magnetic field strength in oersteds is equal to the magnetic field strength in amperes per meter multiplied by 0.0125664.
For example, here's how to convert 10 amperes per meter to oersteds using the formula above.
How Many Oersteds Are in an Ampere per Meter?
There are 0.0125664 oersteds in an ampere per meter, which is why we use this value in the formula above.
Our ampere per meter to oersted calculator automatically converts your magnetic field strength measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Amperes per Meter and oersteds are both units used to measure magnetic field strength. Keep reading to learn more about each unit.
What Is an Ampere per Meter?
SI unit of magnetic field strength (H). It serves as a primary reference unit for measuring magnetic field strength across scientific and practical applications. [1]
The ampere per meter is classified as an International System of Units (SI) unit of magnetic field strength. Amperes per Meter can be abbreviated as A/m; for example, 1 ampere per meter can be written as 1 A/m.
As the primary coherent reference unit for magnetic field strength in this category, all other magnetic field strength units are mathematically anchored to the ampere per meter (A/m).
In practice, amperes per meter (A/m) are widely used across standard magnetic field strength applications within International System of Units (SI) workflows, engineering documentation, and technical data sheets.
What Is an Oersted?
An oersted is a unit of magnetic field strength equal to 79.5774715 amperes per meter (A/m), the base unit for magnetic field strength. CGS magnetizing field unit (1 Oe = 1000/(4π) ≈ 79.57747 A/m). [2]
The oersted is classified as a standard unit of magnetic field strength. Oersteds can be abbreviated as Oe; for example, 1 oersted can be written as 1 Oe.
When working with oersteds (Oe) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, oersteds (Oe) are widely used across standard magnetic field strength applications within international standard workflows, engineering documentation, and technical data sheets.
When converting magnetic field strength between amperes per meter (A/m) and oersteds (Oe), keep full floating-point precision (1 A/m = 0.0125664 Oe; 1 Oe = 79.5774715 A/m) during intermediate calculations and round only the final oersted figure to match your instrument tolerance.
