Convert Nanotesla to Microtesla (nT to µT)
1 nanotesla (nT) = 0.001 microtesla (µT). 1 µT = 1000 nT. Example: 15 nT = 15 × 0.001 = 0.015 µT.

How to Convert Nanotesla to Microtesla
- 1 nT = 0.001 µT
- 1 µT = 1000 nT
- Example: convert 15 nT to µT: 15 nT = 15 × 0.001 µT = 0.015 µT
Formula
µT = nT ÷ 1000
Derivation from SI units:
- 1 nT = 10⁻⁹ T (also called a gamma in geophysics)
- 1 µT = 10⁻⁶ T
- 1 nT = 1 × 10⁻⁹ T ÷ 0.000001 T per µT = 0.001 µT
Both units are defined exactly, so the factor is exact. Nanotesla definition: nanotesla; Microtesla definition: microtesla.
Worked examples
- A reading of 50 nT converts to 0.05 µT.
50 nT × 0.001 = 0.05 µT - A value of 1000 nT is 1 µT.
1000 nT × 0.001 = 1 µT

Frequently asked questions
How many microtesla are in 1 nanotesla?
1 nT = 0.001 µT.
How do I convert nanotesla to microtesla?
Multiply the value in nT by 0.001, or divide it by 1000. For example, 15 nT × 0.001 = 0.015 µT.
Is the nT to µT conversion exact?
Yes. Both units are defined exactly, and 1 nT is exactly 0.001 µT.
