How to convert oersteds to amperes per meter
H-field strength is distinct from B-field flux density in teslas. Their relationship depends on permeability and the material state; no universal conversion from A/m to tesla is applied.
Use x for the value in Oe, b for the intermediate value in A/m, and y for the result in A/m.
A/m = Oe × 79.57747154594767
Worked examples
10 Oe ≈ 795.774715459 A/m
Step 1: (10 × 79.5774715459) ≈ 795.774715459 A/m.
Step 2: 795.774715459 ÷ 1 ≈ 795.774715459 A/m.20 Oe ≈ 1591.54943092 A/m
Step 1: (20 × 79.5774715459) ≈ 1591.54943092 A/m.
Step 2: 1591.54943092 ÷ 1 ≈ 1591.54943092 A/m.
Results are rounded to 12 significant digits. Converting units does not increase the precision of the original measurement. Very large or small values outside JavaScript’s finite numeric range are rejected.
About Oersteds
Oersteds (Oe) measures magnetic field strength under the conventions above. The base value in A/m is (x × 79.5774715459), where x is the numerical value in Oe. Factors shown here are rounded for display; calculations use the stored factor.
About Amperes per meter
Amperes per meter (A/m) measures magnetic field strength under the conventions above. The base value in A/m is (x × 1), where x is the numerical value in A/m. Factors shown here are rounded for display; calculations use the stored factor.
