... The units of B are therefore (H)(A)/m2, but it is more instructive to write webers per meter squared, or Wb/m2, where Wb=(H)(A). But for brevity, and perhaps to honor a deserving scientist, a tesla , T, equivalent to a Wb/m2, is the standard unit adopted by the International System of Units. ...
