Convert Gauss to Kilogauss (G to kG)
1 gauss (G) = 0.001 kilogauss (kG). 1 kG = 1000 G. Example: 15 G = 15 × 0.001 = 0.015 kG.

How to Convert Gauss to Kilogauss
- 1 G = 0.001 kG
- 1 kG = 1000 G
- Example: convert 15 G to kG: 15 G = 15 × 0.001 kG = 0.015 kG
Formula
kG = G ÷ 1000
Derivation from SI units:
- 1 G = 10⁻⁴ T (exact)
- 1 kG = 1000 G = 0.1 T
- 1 G = 0.0001 T ÷ 0.1 T per kG = 0.001 kG
Both units are defined exactly, so the factor is exact. Gauss definition: gauss; Kilogauss definition: kilogauss.
Worked examples
- A reading of 50 G converts to 0.05 kG.
50 G × 0.001 = 0.05 kG - A value of 5000 G is 5 kG.
5000 G × 0.001 = 5 kG

Where it's used
Gauss are used for permanent magnet surface fields (for example 3000–5000 G for neodymium), 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.

Frequently asked questions
How many kilogauss are in 1 gauss?
1 G = 0.001 kG.
How do I convert gauss to kilogauss?
Multiply the value in G by 0.001, or divide it by 1000. For example, 15 G × 0.001 = 0.015 kG.
Is the G to kG conversion exact?
Yes. Both units are defined exactly, and 1 G is exactly 0.001 kG.
