Amperes per Meter to Oersteds Converter (A/m to Oe)
Amperes per Meter to Oersteds Converter (A/m to Oe)
Convert amperes per meter (A/m) to oersteds (Oe) instantly. Divide SI magnetic field strength values by 79.5775 (or multiply by 0.01256637) to convert directly to CGS-Gaussian oersted units.
How to Convert Amperes per Meter to Oersteds
By international electromagnetic definitions:
1 Oe = 1,000 / (4π) A/m ≈ 79.5774715 A/m ≈ 79.5775 A/m
To convert from A/m to Oe, divide by 79.5775 or multiply by 0.01256637:
Oe = A/m ÷ 79.5775 = A/m × 0.01256637
Calculation Examples
- Example 1: Convert 79.5775 A/m to Oe:
79.5775 ÷ 79.5775 = 1 Oe - Example 2: Convert 1,000 A/m to Oe:
1,000 ÷ 79.5775 ≈ 12.5664 Oe - Example 3: Convert 40,000 A/m to Oe:
40,000 ÷ 79.5775 ≈ 502.65 Oe

Frequently Asked Questions
How many Oersteds are in 1 A/m?
One ampere per meter is equal to approximately 0.01256637 oersteds (4π / 1,000 Oe).
Why is 1 Oe equal to 79.5775 A/m?
The oersted is derived in CGS electrostatic/electromagnetic units from Ampere’s law, where the magnetic constant contains a factor of 4π. In SI units, Ampere’s circuital law removes the 4π factor from the definition of H, resulting in the conversion factor 1,000 / (4π) ≈ 79.5774715 A/m.
