Nanotesla quick reference
| Nanotesla | Millitesla | Gauss | Tesla |
|---|---|---|---|
| 1 nT | = 0.000001 mT | = 0.00001 G | = 1e-9 T |
| 10 nT | = 0.00001 mT | = 0.0001 G | = 1e-8 T |
| 100 nT | = 0.0001 mT | = 0.001 G | = 1e-7 T |
| 1000 nT | = 0.001 mT | = 0.01 G | = 0.000001 T |
Where the nanotesla fits
The next larger magnetic flux density unit is the milligauss (mG). 1 nT = 0.01 mG, and 1 mG = 100 nT.
