How to use it
- Type the value in the microteslas 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 = µT × 0.01
Multiply the value in microteslas by 0.01 to get gauss.
Example
To convert 25 µT to gauss: 25 × 0.01 = 0.25 G.

About the units
- Microtesla
- A microtesla is exactly one millionth of a tesla, used for the Earth's field and fields around electrical appliances.
- 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 microtesla?
1 µT = 0.01 G exactly.
How do I convert microteslas to gauss?
Use G = µT × 0.01. For example, 25 µT = 0.25 G.
How many microteslas are in one gauss?
1 G = 100 µT.
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.
