About these units

Metric Ton (t)

Metric (SI)Current unit

1,000 kilograms (about 2,204.6 lb), also spelled tonne. Used for cargo, grain and vehicle weights outside the US.

Barrels gave the tonne its name. The word goes back to a Germanic root for a large cask, the tun, and a full tun could easily weigh around a tonne. In English this became ton; the spelling tonne has been used in France since 1842, where it replaced the older tonneau, and pre-metric French tonnes were 2,000 livres, about 979 kg. Once the metric system took hold, the tonne was fixed at 1,000 kilograms, which is the mass of roughly a cubic metre of water.

The unit is accepted for use with the SI, and its symbol is a lowercase t with no period. Because it sits close to the old English ton, the two get confused: the short ton used in the US is about 10 percent lighter than a tonne, while the long ton differs by less than 2 percent. NIST calls the unit the metric ton, and the spelling tonne is rare in the US. Very large quantities are stated in prefixed forms such as the megatonne, which equals a teragram. In explosives, a tonne of TNT is taken as about 4.2 gigajoules.

1 metric ton = 1,000 kilograms (exactly).

Dram (dr)

US & ImperialTraditional unit (still used in some regions)

One sixteenth of an ounce (1.7718 g). Used mainly for small quantities of powder.

Greek coinage lies behind this small weight: dram is a form of drachma, a coin that was also a unit of mass in ancient Greece. An Attic drachma weighed about 4.37 grams and a Roman one about 3.41 grams. The avoirdupois dram is smaller than both, one sixteenth of an ounce or one 256th of a pound, which is exactly 1.7718451953125 grams, or about 27.34 grains.

A different dram existed in medicine. The apothecaries' dram is an eighth of an apothecaries' ounce and equals 60 grains, or exactly 3.8879346 grams, and it was common in American pharmacy until the mid-twentieth century. After Britain's Weights and Measures Act 1878 the spellings split by about 1900, with dram for the avoirdupois unit and drachm for the apothecaries' one. Today the avoirdupois dram survives mainly in shotgun shell ratings, expressed in drams of black powder equivalent. As a loose word for a small measure of whisky, it has drifted away from the weight altogether.

1 dram = 0.001771845195 kilograms (approximately).
