Magnetic Flux Density Converter
Magnetic flux density, written B, is magnetic flux per unit area — what most people mean by "magnetic field strength" in everyday use. The SI unit is the tesla (T); one gauss is 10⁻⁴ T. The Earth’s field is about 25–65 µT, while hospital MRI scanners typically run at 1.5 or 3 T.
1 Tesla = 10,000 Gauss
How to convert Tesla to Gauss
One Tesla equals 10,000 Gauss, so multiply any value in T by 10,000 to get G. To convert back, divide by 10,000 — or multiply by 0.0001.
G = T × 10,000
Example: 25 T × 10,000 = 250,000 G.
