The ''gauss,'' a unit of magnetic flux density, is named in his honor. It is not a formal part of the SI (metric system), although it is still widely used. The proper SI unit is the ''tesla.'' One tesla = 10<sup>4</sup> gauss. | The ''gauss,'' a unit of magnetic flux density, is named in his honor. It is not a formal part of the SI (metric system), although it is still widely used.
