About these units

Quintal (q)

Metric (SI)Traditional unit (still used in some regions)

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).

Gram (g)

Metric (SI)Current unit

One thousandth of a kilogram. The standard unit for food quantities and small objects.

A gram was once defined as a small drop of the natural world. The French National Convention of 1795 set it as the absolute weight of a volume of pure water equal to a cube one hundredth of a metre on each side, a cubic centimetre. The reference temperature was first the melting point of ice and was later changed to the temperature of maximum density of water, about 4 degrees Celsius. The word came into French as gramme, from Late Latin gramma, itself from the Greek for a letter or small mark; in Late Antiquity it meant about one twenty-fourth of an ounce.

The gram was the base unit of mass in the centimetre-gram-second system, but in 1960 the SI took the kilogram as its base unit, which made the gram one thousandth of it. That is why it appears in so many everyday places: it is the standard for non-liquid ingredients in cooking and shopping, and nutrition labels commonly list contents per 100 g. For a sense of scale, a small paper clip or a pen cap weighs about a gram, and a Japanese 1-yen coin is close to exactly that, while a US penny is around 2.5 g.

1 gram = 0.001 kilograms (exactly).
