Milligauss (mG)
The milligauss is one thousandth of a gauss, equal to 0.1 µT. EMF meters for household and power-line fields commonly read in milligauss.
Symbol: mG
Quantity: magnetic flux density (B field)
SI relation: 1 mG = 1 × 10⁻⁷ T (exact)
Derivation: 1 mG = 10⁻³ G = 10⁻⁷ T = 0.1 µT
Exact: yes, by definition
Typical uses
- EMF meters for homes and offices
- Power-line and appliance magnetic field surveys
Convert milligauss to other units
| Conversion | 1 mG equals | Reverse |
