About these units

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).

Troy Pound (lb t)

Troy & apothecaries'Historical unit (no longer in standard use)

12 troy ounces (373.24 g). Formerly used for precious metals in the UK and US.

Twelve troy ounces made one troy pound, a heavier-feeling number than it sounds because the troy ounce itself is larger than the avoirdupois ounce. The pound holds 5,760 grains, which comes to about 373.24 grams, noticeably lighter than the 453.6 gram avoirdupois pound. The name probably points to the fairs of Troyes in France, although that origin is not certain.

Goldsmiths, silversmiths and mints used it for precious metals, and it was kept in the American system even though people rarely ask for it there today. In Britain the troy pound lost its official status in the nineteenth century, while the troy ounce stayed legal for precious metals.

Everyday use survives only through the ounce. Bullion prices are still quoted per troy ounce, which is one twelfth of this unit, so a troy pound corresponds to twelve of those bullion ounces.

1 troy pound = 0.3732417216 kilograms (exactly).
