Question

If you need to measure the mass of a greeting card you are sending to a friend through the mail, what unit of measurement would you use?

Answer 1

I think it's grams, but I'm not exactly sure, I've never had to weigh a greeting card before lol

Answer 2

The best unit of measurement will be the gram (g).

Step-by-step explanation:

A typical letter has a mass of about 12 g including the envelop (that is if the letter has only one sheet of paper).
