What Is an Oersted?
An oersted is a unit of linear current density equal to 79.5774715 amperes per meter (A/m), the base unit for linear current density. CGS electromagnetic unit equal to 1000/(4π) ≈ 79.5775 A/m. [1]
The oersted is classified as a standard unit of linear current density. 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 linear current density applications within international standard workflows, engineering documentation, and technical data sheets.
What Is an Ampere per Inch?
An ampere per inch is a unit of linear current density equal to 39.3700787 amperes per meter (A/m), the base unit for linear current density. Equal to 39.3701 A/m. [2]
The ampere per inch is classified as a US customary unit of linear current density. Amperes per Inch can be abbreviated as A/in; for example, 1 ampere per inch can be written as 1 A/in.
When working with amperes per inch (A/in) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, amperes per inch (A/in) are widely used across standard linear current density applications within US customary workflows, engineering documentation, and technical data sheets.
When converting linear current density between oersteds (Oe) and amperes per inch (A/in), keep full floating-point precision (1 Oe = 2.0212678 A/in; 1 A/in = 0.494739 Oe) during intermediate calculations and round only the final ampere per inch figure to match your instrument tolerance.
