Convert Microtesla to Nanotesla (µT to nT)
1 microtesla (µT) = 1000 nanotesla (nT). 1 nT = 0.001 µT. Example: 15 µT = 15 × 1000 = 15000 nT.

How to Convert Microtesla to Nanotesla
- 1 µT = 1000 nT
- 1 nT = 0.001 µT
- Example: convert 15 µT to nT: 15 µT = 15 × 1000 nT = 15000 nT
Formula
nT = µT × 1000
Derivation from SI units:
- 1 µT = 10⁻⁶ T
- 1 nT = 10⁻⁹ T (also called a gamma in geophysics)
- 1 µT = 0.000001 T ÷ 1 × 10⁻⁹ T per nT = 1000 nT
Both units are defined exactly, so the factor is exact. Microtesla definition: microtesla; Nanotesla definition: nanotesla.
Worked examples
- A reading of 1 µT converts to 1000 nT.
1 µT × 1000 = 1000 nT - A value of 25 µT is 25000 nT.
25 µT × 1000 = 25000 nT
