Convert Microtesla to Milligauss (µT to mG)
1 microtesla (µT) = 10 milligauss (mG). 1 mG = 0.1 µT. Example: 100 µT = 100 × 10 = 1000 mG.

How to Convert Microtesla to Milligauss
- 1 µT = 10 mG
- 1 mG = 0.1 µT
- Example: convert 100 µT to mG: 100 µT = 100 × 10 mG = 1000 mG
Formula
mG = µT × 10
Derivation from SI units:
- 1 µT = 10⁻⁶ T
- 1 mG = 10⁻³ G = 10⁻⁷ T = 0.1 µT
- 1 µT = 0.000001 T ÷ 1 × 10⁻⁷ T per mG = 10 mG
Both units are defined exactly, so the factor is exact. Microtesla definition: microtesla; Milligauss definition: milligauss.
Worked examples
- The ICNIRP (2010) 50 Hz public reference level of 200 µT is 2000 mG.
200 µT × 10 = 2000 mG - The Earth's field of about 50 µT is 500 mG.
50 µT × 10 = 500 mG
