How to Convert Oersted to Kiloampere per Metre
- 1 Oe = 0.07957747155 kA/m
- 1 kA/m = 12.56637061 Oe
- Example: convert 15 Oe to kA/m: 15 Oe = 15 × 0.07957747155 kA/m = 1.193662073 kA/m
Formula
kA/m = Oe × 0.07957747154595
or kA/m = Oe ÷ 12.56637061436
Derivation from SI units:
- 1 Oe = 1000/(4π) A/m ≈ 79.577 A/m (exact by definition)
- 1 kA/m = 1000 A/m
- 1 Oe = 79.57747154595 A/m ÷ 1000 A/m per kA/m = 0.07957747154595 kA/m
Both units are defined exactly, so the factor is exact. Oersted definition: oersted; Kiloampere per Metre definition: kiloampere per metre.
Worked examples
- A reading of 10 Oe converts to 0.7957747155 kA/m.
10 Oe × 0.07957747155 = 0.7957747155 kA/m - A value of 500 Oe is 39.78873577 kA/m.
500 Oe × 0.07957747155 = 39.78873577 kA/m

Where it's used
Oersteds are used for coercivity of magnets in older and US data sheets, while kiloamperes per metre appear in permanent magnet coercivity (for example 900–2000 kA/m for NdFeB). Both measure magnetic field strength (H field) and coercivity, so the conversion is a fixed factor.

Frequently asked questions
How many kiloamperes per metre are in 1 oersted?
1 Oe = 0.07957747155 kA/m.
How do I convert oersteds to kiloamperes per metre?
Multiply the value in Oe by 0.07957747155, or divide it by 12.56637061. For example, 15 Oe × 0.07957747155 = 1.193662073 kA/m.
Is the Oe to kA/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).
