  a qudt:DerivedUnit, qudt:Unit ;
  dcterms:description """$\\textit{Watt per steradian per square metre}$ is the SI unit of radiance ($W·sr^{-1}·m^{-2}$),
  while that of spectral radiance in frequency is the watt per steradian per square metre
  per hertz ($W·sr^{-1}·m^{-2}·Hz^{-1}$) and that of spectral radiance in wavelength is
  the watt per steradian per square metre, per metre ($W·sr^{-1}·m^{-3}$),
  commonly the watt per steradian per square metre per nanometre ($W·sr^{-1}·m^{-2}·nm^{-1}$).
  It has a dimension of $ML^{-4}T^{-3}$ where $M$ is mass, $L$ is length, and $T$ is time.
  This unit is the standard SI unit in this category."
