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).

Obol (obol)

Ancient GreekHistorical unit (no longer in standard use)Approximate value

One sixth of a drachma, about 0.73 g.

Before coins, Greek bullion money circulated as iron or bronze rods called obeloi, which literally means spits. Six of them could be held in one hand, and that handful gave the drachma its name. When silver coinage appeared, the small coin worth one rod kept the title obol, so a word for a cooking skewer ended up naming the sixth part of a drachma.

On the Attic standard an obol weighed about 0.72 grams, and the figure used here, 0.7277 g, is simply the drachma figure divided by six. Surviving coins vary, and the Aeginetic obol was heavier, near 1.05 grams. Each obol was in turn split into four tetartemoria of about 0.18 grams. The obol was the small change of Athens: jurors were paid in fractions of a drachma, and its weight is comparable to a single paperclip or a small grain of rice, about a fortieth of an ounce.

1 obol = 0.0007276666667 kilograms (approximately).
