Tesla to Gauss Converter — Magnetic Field

Convert magnetic flux density between tesla, millitesla, microtesla, gauss, and gamma.

—
How this conversion works. Flux density is converted through the tesla; the gauss and gamma are exact CGS relations per NIST Special Publication 811.

How to use

  1. Choose the units to convert from and to.

Frequently asked questions

How do I convert tesla to gauss?

1 tesla = 10000 gauss. Choose "Tesla (T)" as From and "Gauss (G)" as To, type a value, and the result updates instantly.

How many gauss is 1 tesla?

Exactly 10,000 G. A 3 T MRI scanner is 30,000 G; a fridge magnet is ~50 G (5 mT); Earth’s field is ~0.5 G (50 µT).

Is this the same as magnetic field strength (H)?

No. This converts flux density B (tesla, gauss). Field strength H uses A/m and oersted — see the Magnetic Field Strength Converter for that quantity.

Is my data sent to a server?

No. Conversions run entirely in your browser using fixed factors — nothing is uploaded or logged.
