# LIGO sensitivity in terms of minimum received power per area

I've been looking at LIGO figures for gravitational wave sensitivity here and it seem to be displayed in an adimensional strain ratio (which I assume that is more or less equivalent to metric perturbation $h_{\mu \nu}/g_{\mu \nu}$, correct me if I'm wrong)

What I'm wondering is how can I convert this sensitivity measure into something like watts/area, as a measure of energy density flux of gravitational waves.

In section 4.5.2: Sensitivity of interferometers in units of energy flux Sathyaprakash and Schutz explain that there is a $4c^3f^2/\pi G$ conversion factor between the noise power spectrum in units of per hertz and the energy density flux in units of Jansky.
