About these units

Long Ton (ton (UK))

Imperial (British)Current unit

2,240 pounds (1,016.05 kg), the imperial or UK ton. Also used for ship displacement.

Before the 15th century an English ton was 2,160 pounds, twenty hundredweight of 108 pounds. Nineteenth-century British definitions included 2,240, 2,352 and 2,400 pounds, though the legal ton was usually 2,240 lb, which is twenty hundredweight of 112 lb. Industry bent the rules: in the 17th and 18th century iron trade, workers were given a 2,240 lb ton of raw material but were expected to return a 2,400 lb ton of processed iron, allowing for waste, and some coal mines delivered long tons but paid miners for a shorter one, which the miners saw as unfair.

The long ton, about 1,016 kg, is within 2 percent of the metric tonne, which makes the two easy to mistake for each other. It is used in the UK, Ireland and most Commonwealth countries that followed the imperial system, although the tonne is now the legal trade unit in the UK, Canada and Australia. Ship displacement has traditionally been quoted in long tons, because a ship cannot be put on a scale and is instead measured by the weight of water it pushes aside. The 2,240 lb figure became the standard for ship design.

1 long ton = 1,016.046909 kilograms (approximately).

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).
