One fluid ounce is the same as 1/8 of a cup or 2 tablespoons. A tablespoon is equal to three teaspoons. Also, one fluid ounce is the same as 25 millilitres.
A standard liquid measuring cup doesn’t usually have a line for 1/8 of a cup, which makes it hard to measure 1 fluid ounce. So, the best way to measure 1 fluid ounce is with measuring spoons like a teaspoon or tablespoon. Most measuring spoons come in a set with 1/4 teaspoon, 1/2 teaspoon, 1 teaspoon, and 1 tablespoon sizes. To get an accurate measurement, the right spoon should be filled to the top without any liquid spilling over.
