How many gauss is 1 millitesla?

1 millitesla equals exactly 10 gauss. The tesla is the SI unit and 1 T = 10,000 G, so 1 mT (0.001 T) = 10 G.

What is the formula for millitesla to gauss?

Gauss = Milliteslas × 10. For example, 50 mT = 500 G.

Which unit is larger, millitesla or gauss?

A millitesla is larger than a gauss. One mT equals 10 G, so values in milliteslas are numerically smaller than their gauss equivalents.

Why are both millitesla and gauss still in use?

Tesla and its subunits (mT, μT) are the SI standard and preferred in physics and medicine. Gauss remains common in engineering, consumer magnets, and older instrumentation that predates widespread SI adoption.

Can I convert gauss back to millitesla with this tool?

Yes. Click the Swap button to switch directions. Millitesla = Gauss ÷ 10.

Conversion Formula

Gauss = Milliteslas × 10

1 tesla = 10,000 gauss, so 1 millitesla (0.001 T) = 10 gauss. The factor is exact by definition.

Quick Reference

Millitesla (mT)	Gauss (G)
0.1 mT	1 G
1 mT	10 G
10 mT	100 G
50 mT	500 G
100 mT	1,000 G
500 mT	5,000 G
1,000 mT	10,000 G

Summary

Convert milliteslas (mT) to gauss (G) — enter a value and get the exact gauss equivalent instantly.

How it works

Enter a millitesla value in the input field.
The converter multiplies by 10 (since 1 mT = 10 G).
