Gauss quick reference
| Gauss | Tesla | Millitesla | Microtesla |
|---|---|---|---|
| 1 G | = 0.0001 T | = 0.1 mT | = 100 µT |
| 10 G | = 0.001 T | = 1 mT | = 1000 µT |
| 100 G | = 0.01 T | = 10 mT | = 10000 µT |
| 1000 G | = 0.1 T | = 100 mT | = 100000 µT |
Where the gauss fits
The next smaller magnetic flux density unit is the microtesla (µT). 1 G = 100 µT, and 1 µT = 0.01 G.
The next larger magnetic flux density unit is the millitesla (mT). 1 G = 0.1 mT, and 1 mT = 10 G.
