Gauss to Milliteslas examples

1 G

1 G × 0.1 = 0.1 mT.

10 G

10 G × 0.1 = 1 mT.

100 G

100 G × 0.1 = 10 mT.

Gauss compared with Milliteslas

One mT is 10 times as large as one G, so your number gets smaller when you convert gauss to milliteslas and bigger when you convert back. If the answer is not smaller than what you typed, you multiplied instead of dividing.

About gauss and milliteslas

Gauss (G): The gauss, exactly 1×10⁻⁴ T. Millitesla (mT): Millitesla, 0.001 T.

How to calculate Gauss to Milliteslas step by step

  1. Enter the value in G (the starting unit).
  2. Multiply by 0.1, because 1 G = 0.1 mT.
  3. The product is the value in mT. To go back, divide by 0.1 or multiply by 10.
