¹ The angstrom is basically defined as 10¯¹º meter. ² There is a variety of
“barrels” established by low or usage. For example, federal taxes on fermented liquors are based on a barrel of 31 gallons; many state laws fix the
“barrel for liquids” at 31 ½ gallons; one state fixes a 36-gallon barrel for cistern measurement; federal law recognizes a 40- gallon barrel for “proof spirits”; by custom, 42 gallons comprise a barrel of crude oil or petroleum products for statistical purposes, and this equivalent is recognized “for liquids” by four states. ³ Frequently recognized as 1 ¼ bushels, struck measure. ¹¹ Used in assaying. The assay ton bears the same relation to the milligram that a ton of 2,000 pounds avoirdupois bears to the ounce troy;
hence the weight in milligrams of precious metal obtained from one assay ton of ore gives directly the number of troy ounces to the net ton. ¹² The gross or long ton and hundredweight are used commercially in the United States to only a limited extent, usually in restricted industrial fields. These units are the same as the British “ton” and “hundredweight”.
