Free Magnetic Field Strength Tool

Convert between 3 supported units including Ampere/meter (A/m), Kiloampere/meter (kA/m), Oersted (Oe) with adjustable precision and a documented conversion methodology.

What this converter covers

Convert magnetic field strength H between amperes per metre, kiloamperes per metre, and oersteds.

Worked example

1 Oersted (Oe) = 79.57747155 Ampere/meter (A/m)

Important unit notes

•This converter is for magnetic field strength H, not magnetic flux density B.
•Oersted is a CGS unit of magnetic field strength; tesla is a unit of magnetic flux density and therefore is not included here.

Conversion factors are maintained against documented standards and definitions. Some displayed decimals are rounded for readability.How accuracy is handled·Sources

About this converter

This tool converts through a consistent base-unit relationship defined for the magnetic field strength. It is designed for quick everyday use while preserving more internal precision than is normally useful to display.
