To send a 1.4-ounce letter in the United States, you typically need two first-class stamps. The standard first-class stamp covers up to 1 ounce, and for each additional ounce, you usually need to add an extra ounce stamp. Therefore, for a letter weighing 1.4 ounces, you'll need one first-class stamp plus an additional ounce stamp.
45 cents for the first ounce and 20 cents for each additional ounce (up to a point).

To determine how many stamps are needed for a 1.1-ounce letter, you typically refer to the current postal rates. As of my last update, a standard First-Class stamp covers letters weighing up to 1 ounce, and an additional ounce usually requires an extra charge. Therefore, you would need one stamp for the first ounce and an additional charge for the extra 0.1 ounce, which could be covered by a second stamp or an additional ounce fee, depending on the specific postal service's rates at the time. Always check with your local postal service for the most accurate and current information.
