About these units
Quintal (q)
100 kilograms. Still used for crop yields in India, France and parts of Europe and South America.
Romance languages gave this unit its name, from the idea of a hundred base units, while German and Russian forms such as Zentner and tsentner follow the same logic. Before metrication a quintal was a hundred of some local pound, so it ranged widely: about 48.95 kilograms in France, around 46 in Spain, about 58.75 in Portugal and 50 in Germany.
The metric quintal fixed the figure at 100 kilograms, the value used here. Farmers in France, Italy, Poland, India and Indonesia still quote yields and prices in it, and wholesale grain in Ethiopia and Eritrea is priced per quintal, as it is in Brazil and some other South American countries. The United States wrote it into law in 1866 as 100 kilograms, though neither the US nor NIST uses it now. English-speaking trade once used the word as another name for the hundredweight, and in Newfoundland a 112 pound quintal was the salt-cod unit into the 1960s.
1 quintal = 100 kilograms (exactly).

Pound (lb)
Exactly 0.45359237 kg, divided into 16 ounces. The standard unit of weight in the US and common in the UK.
Why is pound abbreviated lb? The answer is Roman. The English word comes from the Latin libra pondo, roughly the weight measured in libra, and the symbol keeps the first word. The Roman libra was divided into 12 unciae. The avoirdupois pound of 16 ounces came into general use around 1300 and was initially equal to 6,992 troy grains; under Elizabeth I it was redefined as 7,000 grains. The UK's Weights and Measures Act 1878 set the imperial standard pound as a platinum cylinder, and the troy pound was abolished for trade the following year.
Today the pound is defined from the kilogram. The International Yard and Pound Agreement of 1959 fixed it at exactly 0.45359237 kg, and the UK's Weights and Measures Act 1963 wrote the same figure into law. Pounds remain the everyday unit for body weight, groceries and shipping in the United States and are widely used in the UK. The word also survives in odd places: a six-pounder cannon was named for the weight of its shot, not its own.
1 pound = 0.45359237 kilograms (exactly).
