What is a Magnetic Field Strength Calculator Converter?
A magnetic field strength converter is a tool that converts between units of magnetic field intensity such as ampere per meter, oersted, and kiloampere per meter. It is used in electromagnetic engineering, transformer design, and magnetic material characterization.
How to Convert Magnetic Field Strength Calculator Units
Select the magnetic field strength unit you want to convert from and the target unit using the dropdown menus. Enter your value in the input field and the converter instantly calculates the equivalent field strength. Useful for converting between oersted (CGS) and A/m (SI).

History of Magnetic Field Strength Calculator Measurement
The oersted is named after Hans Christian Ørsted, who discovered that electric currents create magnetic fields in 1820. The ampere per meter is the SI unit of magnetic field strength. The transition from CGS to SI units made oersted-to-A/m conversion a common requirement.
About This Magnetic Field Strength Calculator Converter
This magnetic field strength converter supports 4 units including ampere/meter, ampere turn/meter, kiloampere/meter, and oersted. It handles both SI and CGS magnetic field intensity units used in electromagnetic engineering.
Frequently Asked Questions
How do I convert oersted to ampere per meter?
Multiply the oersted value by 79.5775 to get A/m. For example, 10 Oe × 79.5775 = 795.775 A/m.
What is the difference between oersted and ampere/meter?
Both measure magnetic field strength (H-field). Oersted is the CGS unit and A/m is the SI unit. 1 Oe = 79.5775 A/m. Modern engineering uses A/m, while oersted appears in older literature.
What is magnetic field strength used for?
Magnetic field strength (H-field) describes the magnetizing force in a material. It is used to characterize magnets, design electromagnets, and specify magnetic material properties like coercivity.
Is ampere/meter the same as ampere turn/meter?
Yes, they are numerically identical. Ampere turn/meter explicitly references the coil turns creating the field, while A/m is the general SI unit. Both equal 1 A/m.
What is the difference between B-field and H-field?
H-field (magnetic field strength, in A/m) is the applied magnetizing force. B-field (magnetic flux density, in tesla) is the resulting field including the material's response. They are related by B = µH.
