Magnetic Field Strength Converter
Convert magnetic field strength between amperes per meter, kiloamperes per meter, ampere-turns per meter, and oersteds locally in your browser.
Convert magnetic field strength between amperes per meter, milliamperes per meter, kiloamperes per meter, ampere-turns per meter, and oersteds. Zero is a valid field strength.
Conversions run locally in your browser; your field strength is not uploaded or stored.
Convert one magnetic field strength into the units you need.
Enter a non-negative magnetic field strength and choose its unit to see the equivalent amperes per meter, milliamperes per meter, kiloamperes per meter, ampere-turns per meter, and oersteds. Zero is valid. It runs locally in your browser, so your value is not uploaded or stored.
Frequently Asked Questions
Everything you need to know about this tool, how it works, and privacy.
Which magnetic field strength units can I convert?
Enter a magnetic field strength in amperes per meter, milliamperes per meter, kiloamperes per meter, ampere-turns per meter, or oersteds. The converter returns the equivalent value in all five units using 1 mA/m = 0.001 A/m, 1 kA/m = 1000 A/m, 1 At/m = 1 A/m, and 1 Oe = 1000/(4π) A/m (about 79.5774715459 A/m).
Can I convert zero or decimal field strength values?
Yes. Zero is a valid magnetic field strength, and decimal values are accepted. Negative values are rejected because a field strength magnitude cannot be less than zero. Results show up to six decimal places when needed.
What happens with very large field strength values?
The converter shows an error when the entered field strength is too large to convert safely, instead of returning an unreliable rounded result.
Does my field strength leave my browser?
No. The conversion and copy action run locally in your browser. CodeASystem does not upload or store the value you enter.
