Milliweber (mWb)
The milliweber is one thousandth of a weber, a practical size for flux in transformer and motor cores.
Symbol: mWb
Quantity: magnetic flux
SI relation: 1 mWb = 0.001 Wb (exact)
Derivation: 1 mWb = 10⁻³ Wb
Exact: yes, by definition
Typical uses
- Transformer core flux per turn
- Motor and generator magnetic circuits
Convert milliwebers to other units
| Conversion | 1 mWb equals | Reverse |
|---|---|---|
| milliweber to weber | 0.001 Wb | weber to milliweber |
| milliweber to maxwell | 100000 Mx | maxwell to milliweber |
| milliweber to microweber | 1000 µWb | microweber to milliweber |
