Convert Tesla to Milligauss (T to mG)
1 tesla (T) = 10000000 milligauss (mG). 1 mG = 1 × 10⁻⁷ T. Example: 15 T = 15 × 10000000 = 150000000 mG.

How to Convert Tesla to Milligauss
- 1 T = 10000000 mG
- 1 mG = 1 × 10⁻⁷ T
- Example: convert 15 T to mG: 15 T = 15 × 10000000 mG = 150000000 mG
Formula
mG = T × 10000000
Derivation from SI units:
- 1 T = 1 Wb/m² = 1 kg/(s²·A), the SI unit of magnetic flux density
- 1 mG = 10⁻³ G = 10⁻⁷ T = 0.1 µT
Both units are defined exactly, so the factor is exact. Tesla definition: tesla; Milligauss definition: milligauss.
Worked examples
- A reading of 0.1 T converts to 1000000 mG.
0.1 T × 10000000 = 1000000 mG - A value of 1 T is 10000000 mG.
1 T × 10000000 = 10000000 mG
