Convert Kilogauss to Tesla (kG to T)

Formula

T = kG ÷ 10

Derivation from SI units:

• 1 kG = 1000 G = 0.1 T
• 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. Kilogauss definition: kilogauss; Tesla definition: tesla.

Worked examples

1. A reading of 10 kG converts to 1 T.
   10 kG × 0.1 = 1 T
2. A value of 14 kG is 1.4 T.
   14 kG × 0.1 = 1.4 T

Where it's used

Kilogauss are used for remanence of permanent magnets (for example 12–14 kG for NdFeB), while tesla appear in MRI scanners (1.5 T and 3 T). Both measure magnetic flux density (B field), so the conversion is a fixed factor.
