Milligauss quick reference
| Milligauss | Microtesla | Millitesla | Gauss |
|---|---|---|---|
| 1 mG | = 0.1 µT | = 0.0001 mT | = 0.001 G |
| 10 mG | = 1 µT | = 0.001 mT | = 0.01 G |
| 100 mG | = 10 µT | = 0.01 mT | = 0.1 G |
| 1000 mG | = 100 µT | = 0.1 mT | = 1 G |
Where the milligauss fits
The next smaller magnetic flux density unit is the nanotesla (nT). 1 mG = 100 nT, and 1 nT = 0.01 mG.
The next larger magnetic flux density unit is the microtesla (µT). 1 mG = 0.1 µT, and 1 µT = 10 mG.
