Also, when using TLR metering (these days, who doesnt?), the meter cell itself gets 2 stops less light as well as the film, so no conversion may be needed to begin with.
There are only two reliable ways to get an answer: either read the manual (if available), or make a few test shots.

But actually you could work it out in your head. The same amount of
light is going in; the converter magnifies the image by x2 in both x and
y directions, so it's 4 times the area; ergo you need 4 times the
exposure, or two stops more.
