An average kiwifruit weighs close to 50 grams, and an average lemon would be close to 100 grams. Aside from those discrete items, anything like rice or flour can be measured out to make up 100 grams. For example, 1/2 cup (125 ml or about 4 and 1/2 fl.oz) of dry rice weighs very close to 100 grams.Mar 24, 2007
