Gauss to Milliteslas Converter

Summary

Gauss (G) and millitesla (mT) both measure magnetic flux density (the B-field). Gauss is the CGS unit while millitesla is one-thousandth of the SI unit tesla. The conversion is exact: 1 G = 0.1 mT, or equivalently 10 G = 1 mT. Millitesla is common in Hall-effect sensor datasheets, therapeutic magnet specifications, and industrial magnetic field measurements that fall between the tiny microtesla (geophysics) and the large tesla (MRI) ranges.

How it works

1. Enter your value in gauss into the input field.
2. The converter multiplies the gauss value by 0.1 (exact factor: 1 G = 0.1 mT).
3. Results appear instantly in mT, and also in tesla (T) and microtesla (µT) for cross-reference.
4. Click any result to copy it to your clipboard.
5. Use the quick-example buttons to load common reference values.

Use cases

• Convert Hall-effect sensor readings (often in gauss) to mT for SI datasheets.
• Translate permanent magnet flux density specs between CGS and SI documentation.
• Check earth magnetic field measurements (~0.25–0.65 G = 0.025–0.065 mT).
• Convert fridge magnet ratings (~100 G = 10 mT) for engineering references.
• Cross-reference therapeutic magnetic device specs given in mixed unit systems.
• Quick classroom unit conversion for physics and electrical engineering coursework.
