Convert Millitesla to Microtesla (mT to µT)
1 millitesla (mT) = 1000 microtesla (µT). 1 µT = 0.001 mT. Example: 15 mT = 15 × 1000 = 15000 µT.

How to Convert Millitesla to Microtesla
- 1 mT = 1000 µT
- 1 µT = 0.001 mT
- Example: convert 15 mT to µT: 15 mT = 15 × 1000 µT = 15000 µT
Formula
µT = mT × 1000
Derivation from SI units:
- 1 mT = 10⁻³ T
- 1 µT = 10⁻⁶ T
- 1 mT = 0.001 T ÷ 0.000001 T per µT = 1000 µT
Both units are defined exactly, so the factor is exact. Millitesla definition: millitesla; Microtesla definition: microtesla.
Worked examples
- A reading of 5 mT converts to 5000 µT.
5 mT × 1000 = 5000 µT - A value of 100 mT is 100000 µT.
100 mT × 1000 = 100000 µT

Where it's used
Millitesla are used for fridge and small permanent magnets (about 5–100 mT), while microtesla appear in earth’s magnetic field and compasses. Both measure magnetic flux density (B field), so the conversion is a fixed factor.
