Convert Oersteds to Kilooersteds (Oe to kOe)
1 oersted (Oe) = 0.001 kilooersteds (kOe). 1 kOe = 1000 Oe. Example: 15 Oe = 15 × 0.001 = 0.015 kOe.

How to Convert Oersted to Kilooersted
- 1 Oe = 0.001 kOe
- 1 kOe = 1000 Oe
- Example: convert 15 Oe to kOe: 15 Oe = 15 × 0.001 kOe = 0.015 kOe
Formula
kOe = Oe ÷ 1000
Derivation from SI units:
- 1 Oe = 1000/(4π) A/m ≈ 79.577 A/m (exact by definition)
- 1 kOe = 1000 Oe = 10⁶/(4π) A/m ≈ 79.577 kA/m
- 1 Oe = 79.57747154595 A/m ÷ 79577.47154595 A/m per kOe = 0.001 kOe
Both units are defined exactly, so the factor is exact. Oersted definition: oersted; Kilooersted definition: kilooersted.
Worked examples
- A reading of 10 Oe converts to 0.01 kOe.
10 Oe × 0.001 = 0.01 kOe - A value of 500 Oe is 0.5 kOe.
500 Oe × 0.001 = 0.5 kOe

Where it's used
Oersteds are used for coercivity of magnets in older and US data sheets, while kilooersteds appear in ndFeB and SmCo magnet grades (for example HcJ 12–30 kOe). Both measure magnetic field strength (H field) and coercivity, so the conversion is a fixed factor.

Frequently asked questions
How many kilooersteds are in 1 oersted?
1 Oe = 0.001 kOe.
How do I convert oersteds to kilooersteds?
Multiply the value in Oe by 0.001, or divide it by 1000. For example, 15 Oe × 0.001 = 0.015 kOe.
Is the Oe to kOe conversion exact?
Yes. Both units are defined exactly, and 1 Oe is exactly 0.001 kOe.
