Microtesla (µT)
The microtesla is one millionth of a tesla, equal to 10 milligauss. The Earth’s magnetic field is roughly 25–65 µT depending on location.
Symbol: µT (ASCII: uT)
Quantity: magnetic flux density (B field)
SI relation: 1 µT = 0.000001 T (exact)
Derivation: 1 µT = 10⁻⁶ T
Exact: yes, by definition
Typical uses
- Earth’s magnetic field and compasses
- EMF and power-line field measurements
- Magnetometer readings in phones
