How This Tool Works

This converter changes magnetic field strength between amperes per meter (A/m) and Oersted (Oe). Enter a value in A/m and the result updates immediately using the relationship 1 A/m = 0.01257 Oe.

Use the swap control to convert from Oersted back to A/m. The reverse calculation divides by 0.01257.

  • Input: Magnetic field strength in A/m or Oe.
  • Conversion factor: 1 A/m = 0.01257 Oe.
  • Output: Equivalent magnetic field strength in the opposite unit.

Why This Matters for Magnetics

A/m is the SI unit for magnetic field strength, while Oersted is a CGS unit that still appears in older literature and some engineering specifications. Converting between them keeps H-field measurements comparable across sources.

Keep A/m separate from ampere-meter products such as A*m, which describe different physical quantities and should not use this conversion.

Frequently Asked Questions

Common questions about the A/m to Oe Converter

Magnetic field strength is measured in Tesla (SI) or Gauss (CGS). 1 Tesla = 10,000 Gauss. Earth magnetic field is about 50 microtesla.
