Ounces and pounds are the units of weight which people usually come across on daily basis. However, what many do not understand that while weighing things, it is necessary to keep in mind if you are using ounces or pounds as your unit of measurement. The conversion between ounce and pound can be done easily but one needs to know how to convert ounce to pound and vice versa. The weight of a pound is about 454 grams (approximately 16 ounces), while the weight of an ounce is 28.35 grams. Since both are significantly different, one needs to understand which unit is better for measuring certain things. This is why it becomes important to know how many ounces make up one pound, and vice versa.
