Milligauss to Gauss Converter

1 milligauss (mG) equals 0.001 gauss (G).

Quick answer

  • 1 milligauss = 0.001 gauss
  • 1 gauss = 1,000 milligauss
  • Formula: G = mG ÷ 1,000

1 milligauss = 0.001 gauss

How to convert milligauss to gauss

G = mG ÷ 1,000

To convert milligauss to gauss, divide the number of milligauss by 1,000.

Example: 4 mG to G

  1. Start with the value in milligauss: 4 mG.
  2. Divide by 1,000: 4 ÷ 1,000 = 0.004.
  3. Result: 4 milligauss = 0.004 gauss.

Going the other way, 1 gauss = 1,000 milligauss, so to convert gauss back to milligauss you multiply by the same number. See gauss to milligauss.
