maratoolHow to convert weber to maxwell (magnetic flux)
Type a flux — read Wb, mWb, µWb, Mx, or V·s instantly.
Transformer design notes mix webers, volt-seconds, and (in older US material) maxwells. The Magnetic Flux Converter keeps the 10⁸ jump exact.
How it works
- Pick units — "Weber (Wb)" to "Maxwell (Mx)", or any other pair.
- Type a value — the result updates as you type, with swap and copy.
- Copy — one click, with "Copied!" feedback.
Magnetic flux conversion factors
Every unit converts through the weber (the base unit). To convert A → B, multiply by A's factor and divide by B's:
| Unit | = this many webers |
|---|---|
| Weber (Wb) | 1 |
| Milliweber (mWb) | 0.001 |
| Microweber (µWb) | 1.0000 × 10^-6 |
| Volt-second (V·s) | 1 |
| Tesla square meter (T·m²) | 1 |
| Kilomaxwell (kMx) | 1.0000 × 10^-5 |
| Maxwell (Mx) | 1.0000 × 10^-8 |
When you need it
Flux Φ = B × A: a 1.5 T field through a 10 cm² core carries 1.5 mWb, which is 150,000 Mx. Legacy motor literature’s "kilolines" are kMx — 1 kMx = 10 µWb.
Sources & methodology
Conversion factors follow NIST Special Publication 811; exact-by-definition factors are marked in the tool itself. All math runs client-side in your browser — nothing is uploaded.
