How to Convert Gauss to Millitesla

To convert from Gauss (G) to Millitesla (mT), multiply the value by 0.1.

Formula: mT = G × 0.1

Reverse: G = mT × 10

Step-by-Step Example

Start with your value in Gauss. For example: 5 G
Multiply by the conversion factor: 5 x 0.1
The result is: 0.5 mT

About Gauss

The gauss (G) is a unit of magnetic flux density. One gauss equals 0.0001 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.
