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?
The abbreviation "lb" comes from the Latin word "libra." One pound equals exactly 453.59237 grams. For rough mental math, 1 pound is slightly less than half a kilogram.
