How to use it

  1. Type the value in the gauss box.
  2. Read the result in microteslas as you type, and pick the precision you need.
  3. Swap the direction to convert back, or copy the result.

How it is calculated

µT = G × 100

Multiply the value in gauss by 100 to get microteslas.

Example

To convert 25 G to microteslas: 25 × 100 = 2,500 µT.

About the units

Gauss
The CGS unit of magnetic flux density, corresponding to exactly 0.0001 tesla, still common in magnet specifications.
Microtesla
A microtesla is exactly one millionth of a tesla, used for the Earth's field and fields around electrical appliances.

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 microteslas are in one gauss?

1 G = 100 µT exactly.

How do I convert gauss to microteslas?

Use µT = G × 100. For example, 25 G = 2,500 µT.

How many gauss are in one microtesla?

1 µT = 0.01 G.

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.
