There are 8 Ounces in a cup. Therefore the Tablespoon is 1/2 Ounce. A teaspoon is 1/3 of a tablespoon or 1/6 of an ounce. Remember this, 128 ounces in a gallon. 1/2 of a gallon is the next stop down = 64. 1/2 of that is a quart = 32 ounces. 1/2 of that is a pint = 16 ounces.
The difference between US Letter and Legal Paper sizes and international A4 is discussed here, however it is important to say that Letter is effectively the equivalent to A4 size in the USA.
Today, that is no longer the case. Note: A âlegal padâ does not mean that the paper size on the pad itself is legal-size (8-1/2âW x 14âL), although it can be ordered that way. A Legal Pad just means the paper on the pad has a vertical line drawn down creating a 1-1/4â margin from the left side.
