Long Ton

The long ton, also known as the imperial ton or displacement ton, is a unit of mass in the imperial system of measurements. A long ton is defined as exactly 2,240 pounds. It is used in the United Kingdom and several other Commonwealth countries alongside the mass-based metric tonne defined in 1799.

Grain

The grain or troy grain (symbol: gr) is a unit of mass and it is exactly equal to 64.79891 milligrams. One gram is thus approximately equivalent to 15.43236 grains. The unit formerly used by jewellers to measure pearls, diamonds, and other precious stones, called the jeweller's grain or pearl grain, is equal to 1⁄4 carat (50 mg; 0.77 gr). The grain was also the name of a traditional French unit equal to 53.115 mg. In both British Imperial units and United States customary units, there are precisely 7,000 grains per avoirdupois pound, and 5,760 grains per troy pound or apothecaries' pound.
