These weights are using regular paper from our laser printer (it's doesn't feel either thick or thin.) These were regular (long) mailing envelopes. The scale only weighted to the nearest .1 ounce (it was a scale in the post office), so ...

weighted object

weight

weight per item

7 sheets of paper

1.1 ounces

.157 ounce = 4.45 grams

13 sheets of paper

2.1 ounces

.162 ounce = 4.57 grams

3 envelopes

0.5 ounces

.167 ounce = 4.72 grams

So it looks like you can mail 5 sheets of paper (+envelope) for a 1 ounce (39ยข right now) letter. 11 sheets for 2 ounces.
