About the units
Gauss (G) — The gauss is the CGS magnetic unit (10,000 G = 1 T), named after Carl Friedrich Gauss. Magnet datasheets and older physics texts still quote gauss — the Earth’s magnetic field is conveniently about 0.5 G.
Teslas (T) — The tesla is the SI unit of magnetic flux density, named after Nikola Tesla. It is a big unit: an MRI scanner runs at 1.5–3 T, a fridge magnet manages about 5 mT, and the Earth’s field is a tiny 30–60 µT.
Frequently Asked Questions
What should I check before trusting a G to T result?
Confirm the input value, the unit direction (G to T, not the reverse), and that the formula 1 G = 0.0001 T has been applied.
Is the conversion from G to T exact?
The ratio 0.0001 is defined to high precision and is exact for most practical purposes. Rounding only matters when many decimal places are needed.
How do G and T compare in size?
Compare them through the ratio: 1 G equals 0.0001 T, which shows directly which unit represents a larger amount of Magnetic Field.
How do I convert G to T by hand?
Take the value in G and divide the value by 10000. The result is the same value expressed in T.
Is there a shortcut for converting G to T?
The shortest route is the formula itself: 1 G = 0.0001 T. Memorizing this single line covers every case.
What is the formula to convert G to T?
The formula is 1 G = 0.0001 T. To convert any value, divide the value by 10000.
