Convert Millitesla to Kilogauss (mT to kG)
1 millitesla (mT) = 0.01 kilogauss (kG). 1 kG = 100 mT. Example: 15 mT = 15 × 0.01 = 0.15 kG.

How to Convert Millitesla to Kilogauss
- 1 mT = 0.01 kG
- 1 kG = 100 mT
- Example: convert 15 mT to kG: 15 mT = 15 × 0.01 kG = 0.15 kG
Formula
kG = mT ÷ 100
Derivation from SI units:
- 1 mT = 10⁻³ T
- 1 kG = 1000 G = 0.1 T
- 1 mT = 0.001 T ÷ 0.1 T per kG = 0.01 kG
Both units are defined exactly, so the factor is exact. Millitesla definition: millitesla; Kilogauss definition: kilogauss.
Worked examples
- A reading of 5 mT converts to 0.05 kG.
5 mT × 0.01 = 0.05 kG - A value of 100 mT is 1 kG.
100 mT × 0.01 = 1 kG

Where it's used
Millitesla are used for fridge and small permanent magnets (about 5–100 mT), 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 millitesla?
1 mT = 0.01 kG.
How do I convert millitesla to kilogauss?
Multiply the value in mT by 0.01, or divide it by 100. For example, 15 mT × 0.01 = 0.15 kG.
Is the mT to kG conversion exact?
Yes. Both units are defined exactly, and 1 mT is exactly 0.01 kG.
