Convert Tesla to Nanotesla (T to nT)
1 tesla (T) = 1000000000 nanotesla (nT). 1 nT = 1 × 10⁻⁹ T. Example: 15 T = 15 × 1000000000 = 15000000000 nT.

How to Convert Tesla to Nanotesla
- 1 T = 1000000000 nT
- 1 nT = 1 × 10⁻⁹ T
- Example: convert 15 T to nT: 15 T = 15 × 1000000000 nT = 15000000000 nT
Formula
nT = T × 1000000000
Derivation from SI units:
- 1 T = 1 Wb/m² = 1 kg/(s²·A), the SI unit of magnetic flux density
- 1 nT = 10⁻⁹ T (also called a gamma in geophysics)
Both units are defined exactly, so the factor is exact. Tesla definition: tesla; Nanotesla definition: nanotesla.
Worked examples
- A reading of 0.1 T converts to 100000000 nT.
0.1 T × 1000000000 = 100000000 nT - A value of 1 T is 1000000000 nT.
1 T × 1000000000 = 1000000000 nT
