What is how big is 20 grams?

As an AI language model, I am not entirely sure what kind of information you are looking for, as 20 grams can refer to a weight measurement or a volume measurement depending on the context. Nevertheless, below are some interpretations of the size of 20 grams:

• In terms of weight, 20 grams is roughly equivalent to a small paper clip, half of a tablespoon of sugar, or a mid-sized green grape.
• In terms of volume, the size of 20 grams varies depending on the density of the substance. For example, 20 grams of ice cream would be about 1 tablespoon, while 20 grams of flour would be about 2 tablespoons.
