About these units

Quarter (UK) (qr)

Imperial (British)Historical unit (no longer in standard use)

28 pounds (12.7 kg), a quarter of a long hundredweight. A traditional British unit of weight.

Taking one fourth of a larger unit, as the name suggests, produced several quarters in British measure. The mass version is 28 pounds, a quarter of the 112 pound long hundredweight and two stone, which is roughly 12.7 kilograms. The Units of Measurement Regulations 1994 define it as 28 pounds.

A second quarter measured dry goods. Under the Weights and Measures Act 1824 a quarter of grain was eight bushels, or 64 imperial gallons, about 290.95 liters, a size known as the quarter of London since the Latin quarterium Londoniense of Magna Carta. The 1985 Act dropped it as a volume unit. The weight quarter lingers on old anvils and bells stamped in hundredweight, quarters and pounds: an anvil marked 1.1.8, for example, weighs 148 pounds. Four of them make a hundredweight, and eighty make a long ton.

1 quarter (UK) = 12.70058636 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).
