How to Convert Kilooersted to Ampere per Metre
- 1 kOe = 79577.47155 A/m
- 1 A/m = 0.00001256637061 kOe
- Example: convert 15 kOe to A/m: 15 kOe = 15 × 79577.47155 A/m = 1193662.073 A/m
Formula
A/m = kOe × 79577.47154595
Derivation from SI units:
- 1 kOe = 1000 Oe = 10⁶/(4π) A/m ≈ 79.577 kA/m
- The SI unit of magnetic field strength H
Both units are defined exactly, so the factor is exact. Kilooersted definition: kilooersted; Ampere per Metre definition: ampere per metre.
Worked examples
- A reading of 5 kOe converts to 397887.3577 A/m.
5 kOe × 79577.47155 = 397887.3577 A/m - A value of 12 kOe is 954929.6586 A/m.
12 kOe × 79577.47155 = 954929.6586 A/m

Where it's used
Kilooersteds are used for ndFeB and SmCo magnet grades (for example HcJ 12–30 kOe), while amperes per metre appear in coil and solenoid design. Both measure magnetic field strength (H field) and coercivity, so the conversion is a fixed factor.

Frequently asked questions
How many amperes per metre are in 1 kilooersted?
1 kOe = 79577.47155 A/m.
How do I convert kilooersteds to amperes per metre?
Multiply the value in kOe by 79577.47155. For example, 15 kOe × 79577.47155 = 1193662.073 A/m.
Is the kOe to A/m conversion exact?
Yes. Both units are defined exactly, so the ratio is exact; its decimal form does not terminate and is shown here to 10 significant figures (more with the precision selector).
