Magnetic field
Tesla, gauss, and gamma — SI versus CGS magnetism.
1 Tesla = 10000 Gauss (exact)

How this system works
Earth’s field is tens of microtesla, which is why geophysics still likes the gamma (1 nT). The gauss is the CGS unit: 1 T = 10,000 G. MRI scanners are quoted in tesla.
Base unit: tesla. Tesla is SI; Gauss is CGS.
