Tesla quick reference
| Tesla | Gauss | Kilogauss | Millitesla |
|---|---|---|---|
| 1 T | = 10000 G | = 10 kG | = 1000 mT |
| 10 T | = 100000 G | = 100 kG | = 10000 mT |
| 100 T | = 1000000 G | = 1000 kG | = 100000 mT |
| 1000 T | = 10000000 G | = 10000 kG | = 1000000 mT |
Where the tesla fits
The next smaller magnetic flux density unit is the kilogauss (kG). 1 T = 10 kG, and 1 kG = 0.1 T.
