Gauss to Teslas Converter G → T
1 gauss (G) = 0.0001 teslas (T). Type a value below — the conversion happens instantly, entirely on your device.
1 G = 0.0001 T
1 gauss = 0.0001 teslas
1 × 0.0001 = 0.0001
1 G equals 0.0001 T, so multiplying by 0.0001 converts the value. The result describes the exact same quantity — only the measuring stick changes.
How to convert gauss to teslas
teslas = gauss × 0.0001 — multiply the gauss value by 0.0001.
Example: 10 G = 0.001 T.
To convert the other way: gauss = teslas ÷ 0.0001 — or use the dedicated T to G converter .

About the units
What is a gauss?
The CGS unit of magnetic flux density — exactly 10⁻⁴ tesla, so 1 T = 10,000 G. Still widely used for magnet ratings and Earth's field (~0.5 G).
What is a tesla?
The SI unit of magnetic flux density. A fridge magnet is a few millitesla; an MRI scanner runs at 1.5–3 T. Earth's field is only about 50 microtesla.
Frequently asked questions
How many teslas are in 1 gauss?
1 gauss (G) = 0.0001 teslas (T).
What is the formula to convert gauss to teslas?
teslas = gauss × 0.0001 — multiply the gauss value by 0.0001.
How do I convert G to T without a calculator?
Multiply by 0.0001 for a close estimate. Exact factor: 1 G = 0.0001 T.
Is this G-to-T converter accurate and private?
Yes. It uses the exact internationally defined conversion factors and computes results locally in your browser — your input is never sent to a server, and the page keeps working offline.
