Convert Milligauss to Tesla (mG to T)
1 milligauss (mG) = 1 × 10⁻⁷ tesla (T). 1 T = 10000000 mG. Example: 15 mG = 15 × 1 × 10⁻⁷ = 0.0000015 T.

How to Convert Milligauss to Tesla
- 1 mG = 1 × 10⁻⁷ T
- 1 T = 10000000 mG
- Example: convert 15 mG to T: 15 mG = 15 × 1 × 10⁻⁷ T = 0.0000015 T
Formula
T = mG ÷ 10000000
Derivation from SI units:
- 1 mG = 10⁻³ G = 10⁻⁷ T = 0.1 µT
- 1 T = 1 Wb/m² = 1 kg/(s²·A), the SI unit of magnetic flux density
Both units are defined exactly, so the factor is exact. Milligauss definition: milligauss; Tesla definition: tesla.
Worked examples
- A reading of 2 mG converts to 2 × 10⁻⁷ T.
2 mG × 1 × 10⁻⁷ = 2 × 10⁻⁷ T - A value of 10 mG is 0.000001 T.
10 mG × 1 × 10⁻⁷ = 0.000001 T

Where it's used
Milligauss are used for EMF meters for homes and offices, while tesla appear in MRI scanners (1.5 T and 3 T). Both measure magnetic flux density (B field), so the conversion is a fixed factor.

Frequently asked questions
How many tesla are in 1 milligauss?
1 mG = 1 × 10⁻⁷ T.
How do I convert milligauss to tesla?
Multiply the value in mG by 1 × 10⁻⁷, or divide it by 10000000. For example, 15 mG × 1 × 10⁻⁷ = 0.0000015 T.
Is the mG to T conversion exact?
Yes. Both units are defined exactly, and 1 mG is exactly 1 × 10⁻⁷ T.
