If a recipe asks for 180 g of marshmallow fluff, divide by 128 g per cup to get about 1 3/8 cups. To go back to grams, multiply the cups by 128.

How to measure marshmallow fluff

Thick spreads trap air pockets when you spoon them in. Press the marshmallow fluff into the cup, level it and scrape it out with a spatula. Weighing into a bowl is much easier than scraping a cup.
