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). [1]
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.
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. [2]
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.
When converting magnetic field strength between oersteds (Oe) and amperes per meter (A/m), keep full floating-point precision (1 Oe = 79.5774715 A/m; 1 A/m = 0.0125664 Oe) during intermediate calculations and round only the final ampere per meter figure to match your instrument tolerance.
