Need a refresh!

Its been a long while since I posted and a while since I made up a beer kit. I've made a lot of wine from scratch and have tonight made up a Coopers stout brew which is just starting to ferment. I'll be putting it in my keg when done, but I've forgotten how much sugar to add to the keg for secondary fermentation. 4 oz sticks out in my head...can someone confirm this or tell me how much to add.
I've used dark brown muscovado for this batch as it made it very rich the time before
Many thanks

I put 80g per keg for ales, a bit less for stouts, but not always. But goggle says 80g is just over 2 oz, which makes 4 oz sound like quite a bit to me ?

There are 28 grams in an ounce. Eighty grams is just short of three ounces.
