Weber quick reference
| Weber | Maxwell | Milliweber | Microweber |
|---|---|---|---|
| 1 Wb | = 100000000 Mx | = 1000 mWb | = 1000000 µWb |
| 10 Wb | = 1000000000 Mx | = 10000 mWb | = 10000000 µWb |
| 100 Wb | = 10000000000 Mx | = 100000 mWb | = 100000000 µWb |
| 1000 Wb | = 100000000000 Mx | = 1000000 mWb | = 1000000000 µWb |
Where the weber fits
The next smaller magnetic flux unit is the milliweber (mWb). 1 Wb = 1000 mWb, and 1 mWb = 0.001 Wb.
