Gauss to Tesla Converter
Quick conversion between CGS and SI magnetic field units. Enter gauss to get tesla and milli-tesla, or enter tesla to get gauss. 1 G = 1×10⁻⁴ T = 0.1 mT.
1000 G → 0.1 T → 100 mT
Quick reference table
| Gauss (G) | Tesla (T) | milli-tesla (mT) | Notes |
|---|---|---|---|
| 1 G | 0.0001 T | 0.1 mT | Very weak fields |
| 10 G | 0.001 T | 1 mT | Lab / sensor level |
| 100 G | 0.01 T | 10 mT | Small magnets |
| 1000 G | 0.1 T | 100 mT | Strong magnets |
| 10000 G | 1 T | 1000 mT | 1 tesla |
Formulas
Gauss → Tesla
\( T = G \times 10^{-4} \)
Tesla → Gauss
\( G = T \times 10^{4} \)
Tesla → milli-tesla
\( mT = T \times 1000 \)
Why two systems?
Gauss belongs to the CGS system and is still used by magnet suppliers and older physics notes. Tesla is the SI unit and is standard in engineering, MRI, power devices, and modern scientific papers.
Example
You measure 2500 G on a gaussmeter. Convert to tesla: \( 2500 \times 10^{-4} = 0.25 \) T, i.e. 250 mT.
