About these units

Attic Mina (mina)

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

About 436.6 g, equal to 100 drachmas. A mina of silver was a considerable sum in ancient Athens.

Mina is a borrowed word. It traces back to a Semitic root meaning to count, appearing as manu in Akkadian and maneh in Hebrew, and Greek mna was taken from the same source. In Babylonia the mina was a standard of silver weight by about 2000 BCE, at roughly 570 grams. The Greeks adopted both the word and the sixty-to-one link between mina and talent, but fitted the unit to their own coinage.

The Attic mina of Athens is usually given as about 436.6 grams, the figure used here, though other estimates run a few grams lower, near 431 grams. Cities such as Aegina used a heavier mina of about 624 grams, so a sum in minas meant little without knowing the standard. According to the sources, the mina first counted 70 drachmas and was raised to 100 around the time of Solon, about 594 BC. That decimal relation made it handy for bookkeeping, with 100 drachmas to the mina and 60 minas to the talent. A modern comparison is a little under a pound, about 0.96 pound avoirdupois.

1 Attic mina = 0.4366 kilograms (approximately).

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).
