In the UK: It is best to take the letter to a Post Office. It is not just the weight, but the size and thickness of the envelop that can make a difference.
A quarter-ounce or "quad" can typically cost anywhere from 130-160, and weighs 7 grams.
A (1) ounce letter is $0.44 cents. (2) ounce letter $0.61 cents. (3) ounce letter $0.78 cents. (3.5) ounce letter $0.95 cents. I would personally put (2) $0.44 cent stamps just to make sure, or take it to the post office to weigh it.
Postage was 3 cents for the first ounce. A post card would cost 1 cent.

$30.17I got this by finding how much it is for each ounce (divide 13.20 by 7) then multiplied the price per ounce 1.8857(it keeps going) so I rounded that to 1.89 and multiplied that by 16 (16 ounces in one pound).Cost of 7 oz = $13.20Cost of 1 oz = 13.20/71 lb = 16 ozCost of 16 oz = 13.20 ÷ 7 x 16= $30.17
