megaline Unit Converter

Definition of megaline unit

The megaline is a historical unit of magnetic flux equal to one million magnetic lines. In the centimetre–gram–second electromagnetic system, one line, or maxwell, equals 10⁻⁸ weber; therefore, one megaline equals 10⁻² weber.

History of megaline unit

The megaline developed from the nineteenth-century concept of magnetic lines of force, used to visualize field structure and flux. In the CGS electromagnetic system, James Clerk Maxwell gave the line its later name, with one maxwell defined as one line of magnetic flux. The prefix mega- indicated one million lines, creating the megaline. It appeared in older engineering texts and measurement tables before the weber became the internationally preferred SI unit. Today, the megaline survives mainly as a historical or conversion term.

Applications of megaline unit

Today, the megaline is rarely used in active scientific or industrial measurement, but it can appear in historical specifications, older electromagnetic literature, and unit-conversion references. It is useful when interpreting legacy magnetic data, especially values expressed in lines or maxwells. For modern reporting, the equivalent value is normally given in webers.
