Convert Webers to Milliwebers (Wb to mWb)
1 weber (Wb) = 1000 milliwebers (mWb). 1 mWb = 0.001 Wb. Example: 15 Wb = 15 × 1000 = 15000 mWb.

How to Convert Weber to Milliweber
- 1 Wb = 1000 mWb
- 1 mWb = 0.001 Wb
- Example: convert 15 Wb to mWb: 15 Wb = 15 × 1000 mWb = 15000 mWb
Formula
mWb = Wb × 1000
Derivation from SI units:
- 1 Wb = 1 V·s = 1 T·m², the SI unit of magnetic flux
- 1 mWb = 10⁻³ Wb
Both units are defined exactly, so the factor is exact. Weber definition: weber; Milliweber definition: milliweber.
Worked examples
- A reading of 0.001 Wb converts to 1 mWb.
0.001 Wb × 1000 = 1 mWb - A value of 0.05 Wb is 50 mWb.
0.05 Wb × 1000 = 50 mWb
Weber to Milliweber conversion table
| Webers (Wb) | Milliwebers (mWb) |
|---|---|
| 0.000001 Wb | 0.001 mWb |
| 0.00001 Wb | 0.01 mWb |
| 0.0001 Wb | 0.1 mWb |
| 0.001 Wb | 1 mWb |
| 0.005 Wb | 5 mWb |
| 0.01 Wb | 10 mWb |
| 0.05 Wb | 50 mWb |
| 0.1 Wb | 100 mWb |
| 0.5 Wb | 500 mWb |
| 1 Wb | 1000 mWb |
Where it's used
Webers are used for transformer and motor core flux, while milliwebers appear in transformer core flux per turn. Both measure magnetic flux, so the conversion is a fixed factor.
