What Is a Cup?

The “cup” is an Imperial measurement. The standardized measure of a cup is relatively new. It was initiated by Fannie Farmer the Director of the Boston Cooking School in 1896, and first appeared in her book “The Boston Cooking School Cook Book”. Prior to this it was common for recipes to use terms like a handful of rice or a generous portion of sugar. Now I know people who can cook that way. They just pour in ingredients and their cooking always seems perfect. For the rest of us mere mortals, Fannie Farmer’s standardization was a great service.

What Is a Liter?

The “liter” is a metric measurement. The liter was introduced in France in 1795 by the Republican government after overthrowing the monarchy and all trappings associated with that government, and so began the metric system. In 1901 international agreement was reached to redefined the liter as the space occupied by 1 kg of pure water.
