用法筆記

Oe is an abbreviation for 'oersted'. It is rarely used outside of specialised physics contexts and older scientific literature. Modern research almost always uses the SI unit ampere per metre (A/m) instead.

常見錯誤

❌The field strength was 5 oe, which equals 5 amperes per metre.
✅The field strength was 5 oe, which equals about 398 amperes per metre.
💡One oe is roughly 79.6 A/m, not 1 A/m.
