According to Wikipedia, the pound or pound-mass is a unit of mass used in British imperial and the United States customary systems of measurement.

The term “pound” derives from the Roman unit of measure Libra Pondo, which meant a pound by weight. The English term pound came from the second word pondo in Latin. That is why the pound is abbreviated as “lb.” The “lb” is taken from the first word, Libra!

The pound did not always weigh what it does today. A pound in mediaeval Britain was only 5,400 grains, or the equivalent of 0.350 kg today. The royal mint in the Tower of London kept a standard pound weight. The troy pound, which most likely originated in Troyes, France, displaced the English pound in 1527 with a weight of 6,750 grains, or 0.453 kg today.

Of course, almost no one outside the United States uses the pound today. Only the United States, Liberia, and Myanmar continue to use the pound.

Note: Today, the gram is the most commonly used unit of measurement for non-liquid ingredients in cooking and grocery shopping worldwide. The unit price is normally given per 100 g for food products that are typically sold in quantities far less than 1 kg. Most nutrition labeling standards and legal requirements require relative contents to be stated per 100 g of product so that the resulting figure can also be read as a percentage.
