Convert Tesla to Kilogauss (T to kG)
1 tesla (T) = 10 kilogauss (kG). 1 kG = 0.1 T. Example: 15 T = 15 × 10 = 150 kG.

How to Convert Tesla to Kilogauss
- 1 T = 10 kG
- 1 kG = 0.1 T
- Example: convert 15 T to kG: 15 T = 15 × 10 kG = 150 kG
Formula
kG = T × 10
Derivation from SI units:
- 1 T = 1 Wb/m² = 1 kg/(s²·A), the SI unit of magnetic flux density
- 1 kG = 1000 G = 0.1 T
Both units are defined exactly, so the factor is exact. Tesla definition: tesla; Kilogauss definition: kilogauss.
Worked examples
- A reading of 0.1 T converts to 1 kG.
0.1 T × 10 = 1 kG - A value of 1 T is 10 kG.
1 T × 10 = 10 kG

Where it's used
Tesla are used for MRI scanners (1.5 T and 3 T), while kilogauss appear in remanence of permanent magnets (for example 12–14 kG for NdFeB). Both measure magnetic flux density (B field), so the conversion is a fixed factor.
