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