I'd like to convert this formula

\begin{equation}

l^2 =\frac{c\hbar}{eH}

\end{equation}

where $l$ is a length, and $H$ is in oersted, to SI units.

I am pretty sure it uses CGS, since Oe is mentioned in the text, and its from a theory paper (Kawabata1980, eq.3).

As a plasma physicist I use the NRL Plasma Formulary to convert between CGS and SI units. It can be downloaded from here.

On page 18 it gives you a prescription on how to convert any formula. Remember to convert both sides of the equation. For your problem I get

$$ l^2 = \frac{\varepsilon_0 c^2 \hbar}{eH} $$
