How to Convert Milligauss to Millitesla

To convert from Milligauss (mG) to Millitesla (mT), multiply the value by 1.000000e-4.

Formula: mT = mG × 0.0001

Reverse: mG = mT × 10,000

Step-by-Step Example

Start with your value in Milligauss. For example: 5 mG
Multiply by the conversion factor: 5 x 1.000000e-4
The result is: 0.0005 mT

About Milligauss

The milligauss (mG) is a unit of magnetic flux density. One milligauss equals 1.000000 × 10^-7 base units. UnitConvertLab converts it against every other magnetic flux density unit using this exact definition, so results are reproducible to full double precision rather than rounded lookup tables.

Common uses: magnetic flux density calculations, engineering and science, education.

About Millitesla

The millitesla (mT) is a unit of magnetic flux density. One millitesla equals 0.001 base units. UnitConvertLab converts it against every other magnetic flux density unit using this exact definition, so results are reproducible to full double precision rather than rounded lookup tables.

Common uses: magnetic flux density calculations, engineering and science, education.
