Convert Kilogauss to Nanotesla (kG to nT)

Formula

nT = kG × 100000000

Derivation from SI units:

• 1 kG = 1000 G = 0.1 T
• 1 nT = 10⁻⁹ T (also called a gamma in geophysics)
• 1 kG = 0.1 T ÷ 1 × 10⁻⁹ T per nT = 100000000 nT

Both units are defined exactly, so the factor is exact. Kilogauss definition: kilogauss; Nanotesla definition: nanotesla.

Worked examples

1. A reading of 10 kG converts to 1000000000 nT.
   10 kG × 100000000 = 1000000000 nT
2. A value of 14 kG is 1400000000 nT.
   14 kG × 100000000 = 1400000000 nT

Where it's used

Kilogauss are used for remanence of permanent magnets (for example 12–14 kG for NdFeB), while nanotesla appear in geomagnetic surveys and magnetometers. Both measure magnetic flux density (B field), so the conversion is a fixed factor.
