"The tesla (symbol T) is the derived SI unit of magnetic flux density, which represents the strength of a magnetic field. One tesla represents one weber per square metre. The equivalent, and superseded, cgs unit is the gauss (G); one tesla equals exactly 10,000 gauss."
"As for all eponymous SI units when the unit is written out in full it is not capitalised, but when shortened to its symbol it is capitalised."
