About these units

Tola (tola)

Indian subcontinentTraditional unit (still used in some regions)

180 grains, about 11.6638 g. The traditional South Asian unit for gold and silver, still the basis of gold prices in India, Pakistan and Bangladesh.

Tola comes from a Sanskrit word for weighing, and the unit was traditionally the weight of 100 ratti seeds, the red-and-black seeds of the rosary pea used by Indian goldsmiths. Its weight differed from place to place. Akbar's coins were close to a tola, and Sher Shah Suri's rupee was about one percent lighter than the later British tola.

In 1833 Regulation VII of the British government in India fixed it at 180 troy grains, or about 11.6638 g, exactly three eighths of a troy ounce. The earlier Bengal sicca standard, one Murshidabad rupee, was about 179.67 grains, so this was more tidying up than change. A tola divided into 12 masha of 8 ratti each, and 80 tolas made a seer. Zanzibar's tola was lighter, around 11.34 g. India officially dropped it in 1956, yet gold is still sold by the tola, notably as 10-tola bars, across India, Pakistan, Bangladesh, Nepal and the Gulf.

1 tola = 0.0116638038 kilograms (exactly).

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).
