How to use it
- Type the value in the teslas box.
- Read the result in gauss as you type, and pick the precision you need.
- Swap the direction to convert back, or copy the result.
How it is calculated
G = T × 10,000
Multiply the value in teslas by 10,000 to get gauss.
Example
To convert 25 T to gauss: 25 × 10,000 = 250,000 G.

About the units
- Tesla
- The SI unit of magnetic flux density, equal to one weber per square meter.
- 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 tesla?
1 T = 10,000 G exactly.
How do I convert teslas to gauss?
Use G = T × 10,000. For example, 25 T = 250,000 G.
How many teslas are in one gauss?
1 G = 0.0001 T.
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.
