Convert Gauss to Tesla (G to T)
1 gauss (G) = 0.0001 tesla (T). 1 T = 10000 G. Example: 1000 G = 1000 × 0.0001 = 0.1 T.

How to Convert Gauss to Tesla
- 1 G = 0.0001 T
- 1 T = 10000 G
- Example: convert 1000 G to T: 1000 G = 1000 × 0.0001 T = 0.1 T
Formula
T = G ÷ 10000
Derivation from SI units:
- 1 G = 10⁻⁴ T (exact)
- 1 T = 1 Wb/m² = 1 kg/(s²·A), the SI unit of magnetic flux density
Both units are defined exactly, so the factor is exact. Gauss definition: gauss; Tesla definition: tesla.
Worked examples
- The Earth's field, about 0.5 G, is 0.00005 T.
0.5 G × 0.0001 = 0.00005 T - A 15000 G MRI magnet is 1.5 T.
15000 G × 0.0001 = 1.5 T

Frequently asked questions
How many tesla is 1 gauss?
Exactly 0.0001 T (10⁻⁴ T), by definition of the CGS unit.
Is gauss the same as oersted?
No. Gauss measures flux density B, oersted measures field strength H. They have the same numerical value only in air or vacuum.
How many tesla are in 1 gauss?
1 G = 0.0001 T.
How do I convert gauss to tesla?
Multiply the value in G by 0.0001, or divide it by 10000. For example, 1000 G × 0.0001 = 0.1 T.
Is the G to T conversion exact?
Yes. Both units are defined exactly, and 1 G is exactly 0.0001 T.
