 Inserting the SI units into the above unit correspondences, 
 we find the following conversion factors:
-\begin{equation}
- M_\mathrm{sun} \equiv 1.477\, \mathrm{km} 
-                \equiv 4.92673\, \mathrm{\mu s} 
-                \equiv 8.344956\cdot 10^{15}\, \mathrm{T},
-\end{equation}
+\begin{eqnarray}
+  [L] & = & 1\, M_\mathrm{sun} \equiv 1.477\, \mathrm{km}
+  \\{}
+  [T] & = & 1\, M_\mathrm{sun} \equiv 4.92673\, \mathrm{\mu s}
+  \\{}
+  [B] & = & 1\, \sqrt{\mu_0} /M_\mathrm{sun} \equiv 8.344956\cdot 10^{15}\, \mathrm{T}, 
+\end{eqnarray}
 where T (Tesla) is the magnetic field unit in SI, 
 $1\,\mathrm{T}=1\,\mathrm{N/(A\cdot m)}$, or in its cgs equivalent,
 $1\,\mathrm{Tesla} = 10^4\,\mathrm{Gauss}$.
