Understanding milliwebers to maxwells Conversion
The milliweber (mWb) is one thousandth of a weber, the SI unit of magnetic flux, and is used when describing the flux threading small coils, sensors, and transformer windings. The maxwell (Mx) is the CGS unit of magnetic flux, equal to one gauss over one square centimetre, and still appears in magnetics engineering and older physics texts. Converting milliwebers to maxwells links modern SI magnetic-circuit figures to the CGS units common in permanent-magnet and transformer literature.
Conversion Formula
To convert milliwebers to maxwells, multiply by this factor:

How to Convert milliwebers to maxwells
Move from the SI flux unit to the CGS maxwell with a single multiplication.
- Recall the factor: One milliweber equals 100,000 maxwells.
- Take your value: Note the magnetic flux in milliwebers.
- Multiply: Multiply that value by 100,000 to get maxwells.
- Result: For 25 mWb, the result is 25 × 100,000 = 2,500,000 Mx.

What is the milliweber?
The milliweber is a submultiple of the weber, the SI unit of magnetic flux, equal to one-thousandth of a weber. It is convenient for describing the modest flux levels found in transformer cores, motors, and inductors.
Definition
One milliweber is 10⁻³ weber:
Because the weber equals 1 V·s = 1 T·m², a milliweber corresponds to a volt-second of 0.001 V·s, or a magnetic flux density of one tesla passing through an area of 10 cm² (0.001 m²). It also equals 10⁵ maxwells.
Origin and History
The milliweber inherits its name from Wilhelm Eduard Weber (1804–1891), whose surname was adopted for the SI flux unit in the twentieth century. The "milli-" prefix, from the Latin for one-thousandth, has been part of the metric system since its late-eighteenth-century origins.
Law and Notable Facts
As an SI-prefixed unit, the milliweber is fully official within the International System. Engineers favour it because transformer and inductor flux values often fall in the milliweber range, keeping numbers readable rather than resorting to small fractions of a weber.
Real-World Examples and Conversions
- 1 mWb = 0.001 Wb = 10⁵ maxwells.
- A 0.5 T field through a 20 cm² pole face gives 1 mWb of flux.
- 1000 mWb = 1 Wb.
- A coil with 1 mWb linking 200 turns has a flux linkage of 0.2 Wb-turns.
What is the maxwell?
The maxwell is the CGS-Gaussian unit of magnetic flux, representing the flux through one square centimetre of area in a field of one gauss. It survives in older electrical-engineering texts and legacy magnetics work.
Definition
One maxwell equals one gauss-square-centimetre, which converts to 10⁻⁸ weber in SI units:
Since 1 gauss = 10⁻⁴ tesla and 1 cm² = 10⁻⁴ m², the product is 10⁻⁸ T·m² = 10⁻⁸ Wb. Conversely, 1 weber = 10⁸ maxwells.
Origin and History
The unit is named after the Scottish physicist James Clerk Maxwell (1831–1879), whose equations unified electricity, magnetism, and light. Originally called the "line" of magnetic force in the CGS system, it was renamed the maxwell by the International Electrotechnical Commission around 1900.
Law and Notable Facts
The maxwell is not an SI unit and its use is deprecated in favour of the weber, though it persists in the phrase "lines of flux," since one maxwell corresponds to a single line of magnetic induction in the classical field-line picture.
Real-World Examples and Conversions
- 1 Mx = 10⁻⁸ Wb; 1 Wb = 100,000,000 Mx.
- A 1 gauss field through 1 cm² produces exactly 1 maxwell.
- 1 mWb = 100,000 Mx.
- The Earth's field through a 1 cm² loop yields roughly 0.5 Mx.
Frequently Asked Questions
How many maxwells are in one milliweber?
One milliweber equals 100,000 maxwells, because one weber is 10⁸ maxwells and a milliweber is a thousandth of that.
How do I convert milliwebers to maxwells?
Multiply the milliweber value by 100,000. For example, 25 mWb equals 2,500,000 Mx.
What is a maxwell used for?
The maxwell is the CGS unit of magnetic flux, used in magnetics design, permanent-magnet specifications, and older engineering references where flux is stated in lines per square centimetre.
How many milliwebers equal one maxwell?
One maxwell equals 0.00001 milliwebers, the reciprocal of the forward factor.
How does the maxwell relate to the gauss?
One maxwell is the flux produced by a field of one gauss passing through one square centimetre, tying the flux unit directly to the CGS flux-density unit.
