How to Convert Oersted to Ampere per Centimetre
- 1 Oe = 0.7957747155 A/cm
- 1 A/cm = 1.256637061 Oe
- Example: convert 15 Oe to A/cm: 15 Oe = 15 × 0.7957747155 A/cm = 11.93662073 A/cm
Formula
A/cm = Oe × 0.7957747154595
or A/cm = Oe ÷ 1.256637061436
Derivation from SI units:
- 1 Oe = 1000/(4π) A/m ≈ 79.577 A/m (exact by definition)
- 1 A/cm = 100 A/m
- 1 Oe = 79.57747154595 A/m ÷ 100 A/m per A/cm = 0.7957747154595 A/cm
Both units are defined exactly, so the factor is exact. Oersted definition: oersted; Ampere per Centimetre definition: ampere per centimetre.
Worked examples
- A reading of 10 Oe converts to 7.957747155 A/cm.
10 Oe × 0.7957747155 = 7.957747155 A/cm - A value of 500 Oe is 397.8873577 A/cm.
500 Oe × 0.7957747155 = 397.8873577 A/cm

Where it's used
Oersteds are used for coercivity of magnets in older and US data sheets, while amperes per centimetre appear in magnetic particle inspection (tangential field, for example 20–60 A/cm). Both measure magnetic field strength (H field) and coercivity, so the conversion is a fixed factor.

Frequently asked questions
How many amperes per centimetre are in 1 oersted?
1 Oe = 0.7957747155 A/cm.
How do I convert oersteds to amperes per centimetre?
Multiply the value in Oe by 0.7957747155, or divide it by 1.256637061. For example, 15 Oe × 0.7957747155 = 11.93662073 A/cm.
Is the Oe to A/cm 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).
