About these units

Hundredweight (US) (cwt (US))

US customaryTraditional unit (still used in some regions)

100 pounds (45.36 kg), also called the short hundredweight or cental.

Hundredweight is a half-translated Latin idea: centum means one hundred, and medieval English merchants spoke of a centum weight or quintal. Around 1300 several different hundreds were in use as weights. The British version was fixed at 8 stone, or 112 pounds (50.80 kg), by the Weights and Measures Act 1835, so that 20 of them made a long ton of 2,240 pounds. The United States and Canada instead adopted a plain 100 pounds, the figure of 45.36 kg used here.

That round American hundredweight is also called the short hundredweight, and 20 of them make the 2,000-pound short ton. Britain's 1824 act had barred a 100-pound measure because of fraud concerns, but in 1879 it was legalised there as the cental, after merchants importing American wheat and tobacco pressed for it. In the US the unit survives in livestock sales, some grains and oilseeds, paper and certain futures contracts. NIST lists it as 100 lb, about 45.359 kg.

1 hundredweight (US) = 45.359237 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).
