What is being measured?
Magnetic flux describes the magnetic field integrated over a specified surface. A flux unit is different from a flux-density unit.
Flux and flux density differ by area. Maxwell is CGS EMU.
Meaning of mWb
Milliwebers uses the symbol mWb in this library and measures magnetic flux. Under the stated reference convention, 1 mWb = approximately 0.001 Wb. This equivalence changes how a known value is written. It does not increase measurement accuracy or establish whether a measurement is appropriate to a real application.
Conversion method
Multiply the value by the source factor (0.001), then divide by the target factor (1). The factor ratio expresses the same magnetic flux measurement in the other unit.
Worked example
For a known value of 10 mWb, the reference conversion gives 0.01 Wb. Converting that result back gives approximately 10 mWb. This reverse check helps catch a reversed factor, but matching round-trip arithmetic alone does not independently verify a source definition.
Common reference values
| Input (mWb) | Reference equivalent (Wb) |
|---|---|
| 1 | 0.001 |
| 5 | 0.005 |
| 10 | 0.01 |
| 25 | 0.025 |
| 50 | 0.05 |
| 100 | 0.1 |
Compare one mWb with other units
| Target unit | Equivalent of 1 mWb | Definition guide |
|---|---|---|
| Webers (Wb) | 0.001 | Read definition |
| Microwebers (µWb) | 1000 | Read definition |
| Nanowebers (nWb) | 1000000 | Read definition |
| Maxwells (Mx) | 100000 | Read definition |
| Picowebers (pWb) | 1000000000 | Read definition |
Precision and common mistakes
- Keep the source and target quantity consistent. A matching symbol is not enough to establish a compatible definition.
- Record the original measurement precision. Showing twelve significant digits in a table does not make a rounded input more precise.
- Check symbol capitalization, prefixes and any regional convention in the source. Use the displayed unit definition rather than a similarly named unit.
- Factors involving repeating fractions or π use finite numerical precision. Round the final answer to the precision justified by your input.
