Short background on the units used in this conversion.
The oersted (Oe) equals exactly 79.5774715459 ampere per meter — the CGS unit of magnetic field strength (H), pinned to 1000/(4π) A/m.
Oersteds label demagnetization curves, legacy datasheets, and CGS magnetic specifications alongside gauss.
Ampere per meter (A/m) is the SI unit of magnetic field strength H — the magnetizing field in free space and magnetic materials.
A/m quantifies H-field in Maxwell’s equations, magnetic shielding design, and SI engineering references.
A/m = Oe × 79.5774715459Oe = A/m × 0.012566370614, using the same exact factors as this converter.
