You can safely mail 5 pages of 8-1/2 x 11 inch 20# basis paper, plus envelope and stamp, with enough postage to send one ounce. This is the stuff that people usually feed office copiers with.

Incidentally, a ream of 500 sheets of 8-1/2 x 11 inch 20# paper weighs almost exactly 5 pounds, which is 80 ounces. This comes out to 6-1/4 sheets per ounce, so you would be overweight if you stuck a sixth page in your letter.

If you went with heavier weight paper, you would have correspondingly fewer sheets per ounce. 24# paper weighs almost exactly 6 pounds per 500-sheet ream of 8-1/2 x 11 inch stock. This would come out to slightly more than 5 sheets per ounce. You could mail only a 4-page letter on that kind of paper.

Based on a standard sheet of A4 paper, in a standard C5 envelope I would say 15grams.

Why, postage is based on the size of the envelope not its weight.
