Millitesla (mT)
The millitesla is one thousandth of a tesla, equal to 10 gauss. It is a convenient unit for magnets, sensors and magnetic particle testing.
Symbol: mT
Quantity: magnetic flux density (B field)
SI relation: 1 mT = 0.001 T (exact)
Derivation: 1 mT = 10⁻³ T
Exact: yes, by definition
Typical uses
- Fridge and small permanent magnets (about 5–100 mT)
- Hall-effect sensor ranges
- Magnetic particle inspection field strength
Convert millitesla to other units
| Conversion | 1 mT equals | Reverse |
