Magnetic Flux Density Converter
Magnetic flux density — often just called the magnetic field — is flux per unit area. The SI unit is the tesla; the CGS gauss is ten thousand times smaller and still standard in magnet catalogues. For scale, Earth's field is about half a gauss, a fridge magnet is around 50 gauss, and an MRI scanner runs at 1.5 to 3 tesla.

About magnetic flux density conversion
Magnetic Flux Density conversion is commonly needed when magnet selection, MRI, motor design, and geomagnetic surveys. Earth's field is roughly half a gauss, so most everyday magnet readings sit in the gauss-to-kilogauss range rather than in tesla.
