What is being measured?
Magnetic field strength is kept separate from magnetic flux density. A universal conversion from ampere per metre to tesla is not provided.
Oersted factor is 1000/(4π), not exact finite decimal. Do not convert H to tesla without permeability.
Choose a unit definition
Symbols, prefixes and conventions matter. Each row links to a definition, a worked example and a comparison table. Units of different quantities are kept separate even when symbols or dimensions look similar.
Amperes per meter (A/m)
Definition, reference values and linked conversions.
Kiloamperes per meter (kA/m)
Definition, reference values and linked conversions.
Amperes per centimeter (A/cm)
Definition, reference values and linked conversions.
Oersteds (Oe)
Definition, reference values and linked conversions.
Choose the conversion direction
Start with the unit attached to the original measurement. Select the unit needed by the receiving report, specification or formula. Conversion tools preserve the measured quantity; calculating another property can require additional measured inputs and assumptions.
Precision and common mistakes
- Keep the source and target quantity consistent. A matching symbol is not enough to establish a compatible definition.
- Record the original measurement precision. Showing twelve significant digits in a table does not make a rounded input more precise.
- Check symbol capitalization, prefixes and any regional convention in the source. Use the displayed unit definition rather than a similarly named unit.
- Factors involving repeating fractions or π use finite numerical precision. Round the final answer to the precision justified by your input.
