To convert kilogauss to milliteslas, multiply by 100. That factor is the whole relationship: both units measure the strength of a magnetic field, so the conversion is a proportion with no offset and no substance-specific constant.
Kilogauss rates permanent magnets: a strong neodymium magnet is around 12 to 14 kG at the pole face. One milli tesla is one thousandth of a tesla (1e-3 teslas).
Below the calculator there is a step table for the values people look up most, and a second table putting real the strength of a magnetic field figures into milliteslas so the number you get has something to be compared against.
The formula
kilogauss- The amount you are converting, in kilogauss
100- The exact number of milliteslas in one kilogauss
milliteslas- The converted result
How it works, step by step
- Enter the value in kilogauss.
- It is multiplied by 100, the exact factor between the two units.
- The answer is shown in milliteslas, with the reverse conversion beneath it.
- Check the reference table if you want a figure of comparable size.
Worked examples
MRI scanner: 30 kG in milliteslas
Take mri scanner, roughly 30 kG. The conversion is a single multiplication — 30 × 100 — giving 3000 mT. Because the relationship is proportional, doubling the input doubles the answer to 6000 mT.
Neodymium magnet, pole face: 13 kG in milliteslas
At 13 kG (neodymium magnet, pole face), the same quantity in milliteslas is 13 × 100 = 1300 mT. One kilogauss is 100 milliteslas, so the numbers grow as expected.
How to read your score
Frequently asked questions
How many milliteslas are in one kilogauss?
Exactly 100. Every figure on this page is that one number multiplied by your input, so the only rounding is at the display step.
What is the formula to convert kilogauss to milliteslas?
milliteslas = kilogauss × 100. Reversed, kilogauss = milliteslas ÷ 100, which is the same as multiplying by 0.01.
Which is the bigger unit, the kilogauss or the millitesla?
The kilogauss. One kilogauss equals 100 milliteslas.
What does this quantity actually measure?
Both units measure the strength of a magnetic field. That is why a single factor is enough: there is no temperature offset and no material property involved, unlike conversions that cross between different quantities.
What is a kilogauss?
Kilogauss rates permanent magnets: a strong neodymium magnet is around 12 to 14 kG at the pole face.
What is a millitesla?
One milli tesla is one thousandth of a tesla (1e-3 teslas).
Why does my answer differ from another converter?
Almost always because the other tool rounded the factor before multiplying. This page keeps full double precision through the calculation and rounds only for display, and it prints the factor it used so you can see where any difference came from.
