This page converts kilogauss into teslas using the factor 0.1, and shows the reverse figure alongside it. Both units measure the strength of a magnetic field, which is why one number does the whole job.
Kilogauss rates permanent magnets: a strong neodymium magnet is around 12 to 14 kG at the pole face. The tesla is the SI unit of magnetic flux density. One tesla is a very strong field: an MRI scanner runs at 1.5 to 3 T.
The tables underneath give both a plain step-by-step lookup and a list of real quantities expressed in teslas, so you can sanity-check whether your answer is a plausible size.
The formula
kilogauss- The amount you are converting, in kilogauss
0.1- The exact number of teslas in one kilogauss
teslas- The converted result
How it works, step by step
- Enter the value in kilogauss.
- It is multiplied by 0.1, the exact factor between the two units.
- The answer is shown in teslas, with the reverse conversion beneath it.
- Check the reference table if you want a figure of comparable size.
Worked examples
Speaker gap: 10 kG in teslas
Take speaker gap, roughly 10 kG. The conversion is a single multiplication — 10 × 0.1 — giving 1 T. Because the relationship is proportional, doubling the input doubles the answer to 2 T.
Earth's field: 0.0005 kG in teslas
Take earth's field, roughly 0.0005 kG. The conversion is a single multiplication — 0.0005 × 0.1 — giving 5e-05 T. Because the relationship is proportional, doubling the input doubles the answer to 0.0001 T.
How to read your score
Frequently asked questions
How many teslas are in one kilogauss?
Exactly 0.1. 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 teslas?
teslas = kilogauss × 0.1. Reversed, kilogauss = teslas ÷ 0.1, which is the same as multiplying by 10.
Which is the bigger unit, the kilogauss or the tesla?
The tesla. One kilogauss is only 0.1 of a tesla, so it takes 10 kilogauss to make one tesla.
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 tesla?
The tesla is the SI unit of magnetic flux density. One tesla is a very strong field: an MRI scanner runs at 1.5 to 3 T.
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.
