Understanding the Units

What is a Cup?

In US cooking, a cup measures volume, not weight. One standard US cup holds 236.588 ml of liquid. Because different ingredients have different densities, a cup of one ingredient can weigh very differently from a cup of another.

What is a Pound?

A pound (lb) is a US customary unit of weight equal to 453.592 grams or 16 ounces. It is used for larger quantities of ingredients like flour, sugar, and meat.
