About the units
- Millitesla
- A millitesla is exactly one thousandth of a tesla, which is 10 gauss.
- Gauss
- The CGS unit of magnetic flux density, corresponding to exactly 0.0001 tesla, still common in magnet specifications.
Limits and caveats
- Results are rounded for display and computed with the browser's floating point precision (about 15 significant digits).
- Both unit factors are exact by their official definitions.
Questions about this tool
How many gauss are in one millitesla?
1 mT = 10 G exactly.
How do I convert milliteslas to gauss?
Use G = mT × 10. For example, 25 mT = 250 G.
How many milliteslas are in one gauss?
1 G = 0.1 mT.
How many gauss are in one tesla?
One tesla is exactly 10000 gauss, so a 1.5 tesla MRI scanner is 15000 gauss.
How strong is the Earth's magnetic field?
At the surface it ranges from about 25 to 65 microteslas depending on location, roughly 0.25 to 0.65 gauss.
