milliweber [mWb] Unit Converter

Definition of milliweber [mWb] unit

The milliweber (mWb) is a derived SI unit of magnetic flux equal to one-thousandth of a weber: 1 mWb = 10⁻³ Wb. It measures the total magnetic field passing through a specified surface under defined conditions.

History of milliweber [mWb] unit

The milliweber derives from the weber, the SI unit named after German physicist Wilhelm Eduard Weber, whose nineteenth-century investigations helped establish electromagnetic measurement. The weber was adopted within the modernized metre-kilogram-second system and later incorporated into the International System of Units (SI). As a decimal submultiple, the milliweber uses the prefix “milli-,” meaning one thousandth, from the metric system. It became especially practical in engineering documentation, where magnetic flux values in sensors, transformers, and machines are often more conveniently expressed in milliwебers than in whole webers.

Applications of milliweber [mWb] unit

Today, milliwебers are used to specify magnetic flux in small transformers, inductors, relays, motors, and magnetic sensors. They appear in component datasheets, calibration procedures, and laboratory measurements, particularly when flux levels are far below one weber. For example, a sensor may measure a changing flux of several milliwебers, supporting circuit design and performance analysis.
