I'm not certain about grams per gallon (why are you mixing metric and english?). The general rule for wine (and probably cider as well) is one campden tablet or 1/8th tsp of k-meta per gallon.

According to wikipedia one campden tablet typically weighs .44 grams and 10 campden tablets equals 1 tsp of k-meta so I'd guess between .44 and .55 grams of k-meta per gallon. (1/8th of 4.4g is .55g)

Adding a little extra won't hurt, especially if your wine or cider is done fermenting.
