Convert Nanotesla to Tesla (nT to T)
1 nanotesla (nT) = 1 × 10⁻⁹ tesla (T). 1 T = 1000000000 nT. Example: 15 nT = 15 × 1 × 10⁻⁹ = 1.5 × 10⁻⁸ T.

How to Convert Nanotesla to Tesla
- 1 nT = 1 × 10⁻⁹ T
- 1 T = 1000000000 nT
- Example: convert 15 nT to T: 15 nT = 15 × 1 × 10⁻⁹ T = 1.5 × 10⁻⁸ T
Formula
T = nT ÷ 1000000000
Derivation from SI units:
- 1 nT = 10⁻⁹ T (also called a gamma in geophysics)
- 1 T = 1 Wb/m² = 1 kg/(s²·A), the SI unit of magnetic flux density
Both units are defined exactly, so the factor is exact. Nanotesla definition: nanotesla; Tesla definition: tesla.
Worked examples
- A reading of 50 nT converts to 5 × 10⁻⁸ T.
50 nT × 1 × 10⁻⁹ = 5 × 10⁻⁸ T - A value of 1000 nT is 0.000001 T.
1000 nT × 1 × 10⁻⁹ = 0.000001 T

Where it's used
Nanotesla are used for geomagnetic surveys and magnetometers, while tesla appear in MRI scanners (1.5 T and 3 T). Both measure magnetic flux density (B field), so the conversion is a fixed factor.

Frequently asked questions
How many tesla are in 1 nanotesla?
1 nT = 1 × 10⁻⁹ T.
How do I convert nanotesla to tesla?
Multiply the value in nT by 1 × 10⁻⁹, or divide it by 1000000000. For example, 15 nT × 1 × 10⁻⁹ = 1.5 × 10⁻⁸ T.
Is the nT to T conversion exact?
Yes. Both units are defined exactly, and 1 nT is exactly 1 × 10⁻⁹ T.
